129-526: The National Sea Life Centre is an aquarium with over 60 displays of freshwater and marine life in Brindleyplace , Birmingham , England . Its ocean tank has a capacity of 1,000,000 litres (220,000 imp gal) of water and houses giant green sea turtles , blacktip reef sharks and tropical reef fish, with the only fully transparent 360-degree underwater tunnel in the United Kingdom . The building

258-468: A saltwater aquarium , though he did not use the term. In 1846, Anne Thynne maintained stony corals and seaweed for almost three years, and was credited as the creator of the first balanced marine aquarium in London. English chemist Robert Warington experimented with a 13-gallon container, which contained goldfish, eelgrass , and snails , creating one of the first stable aquaria. The aquarium principle

387-414: A 400-litre (110 US gal; 88 imp gal) tank with many other fish in it represents only a minor change. For this reason, hobbyists often favor larger tanks, as they require less attention. Several nutrient cycles are important in the aquarium. Dissolved oxygen enters the system at the surface water-air interface. Similarly, carbon dioxide escapes the system into the air. The phosphate cycle

516-1156: A challenge to recreate such environments, and most "true" biotopes will only have a few (if not only one) species of fish and invertebrates. Finally, an emerging concept for the home is that of a wall mounted aquarium, some of which are displayed at the Living Art Marine Center . An aquarium can range from a small glass bowl containing less than 1 litre (2.1 US pt) of water to immense public aquaria that house entire ecosystems such as kelp forests . Relatively large home aquaria resist rapid fluctuations of temperature and pH , allowing for greater system stability. Beginner aquarists are advised to consider larger tanks to begin with, as controlling water parameters in smaller tanks can prove difficult. Small, unfiltered bowl-shaped aquaria are now widely regarded as unsuitable for most fish. In order to keep water conditions at suitable levels, aquariums should contain at least two forms of filtration : biological and mechanical. Chemical filtration should also be considered under some circumstances for optimum water quality. Chemical filtration

645-420: A circular, submerged lid. Pseudokreisels are "U" or semicircle shaped, usually without a lid. Stretch kreisels are a "double gyre" kreisel design, where the tank length is at least twice the height. Using two downwelling inlets on both sides of the tank lets gravity create two gyres in the tank. A single downwelling inlet may be used in the middle as well. The top of a stretch kreisel may be open or closed with

774-556: A container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, The Aquarium: An Unveiling of the Wonders of the Deep Sea in 1854. Small aquariums are kept in

903-425: A cooler environment. Temperature consistency is more important than range. Most organisms are not accustomed to sudden changes in temperatures, which can cause shock and lead to disease. Water temperature can be regulated with a thermostat and heater (or cooler). Water movement can also be important in simulating a natural ecosystem. Aquarists may prefer anything from still water up to swift currents , depending on

1032-444: A dazzling aquarium is one of the last surefire ways to impress their peers." A kreisel tank ( kreisel being German for " spinning top " or " gyroscope ") is an aquarium shaped like a horizontal cylinder that is designed to hold delicate animals such as jellyfish and newborn seahorses. These aquariums provide slow, circular water flow with a bare minimum of interior hardware to prevent the inhabitants from becoming injured by pumps or

1161-489: A fortune-teller and seer. In 1344, during a plague epidemic, Zhu Yuanzhang's parents and two brothers died. He managed to survive by entering a local Buddhist monastery, which was later closed due to a lack of funds. For the next three years, Zhu wandered as a mendicant monk, becoming familiar with the landscape and people of eastern Henan and northern Anhui. He then returned to the monastery in 1348 and stayed for four years, during which he learned to read, write, and study

1290-578: A group of military and civilian figures, but the civil officials never attained the same level of prestige and influence as the military. In 1367, he granted the title of duke ( gong ) to three of his closest collaborators—generals Xu Da and Chang Yuchun , and official Li Shanchang . After the establishment of the Ming dynasty, he also bestowed ranks and titles upon a wider circle of loyal generals. These military leaders were chosen based on their abilities, but their positions were often inherited by their sons. As

1419-399: A lid. There may also be screens about midway down the sides of the tank, or at the top on the sides. It is possible to combine these designs; a circular shaped tank is used without a lid or cover, and the surface of the water acts as the continuation of circular flow. Another popular setup is the biotope aquarium. A biotope aquarium is a recreation of a specific natural environment. Some of

1548-514: A natural water source (such as a river, lake, or ocean) to reduce the level of treatment. Some hobbyists use an algae scrubber to filter the water naturally. Water temperature determines the two most basic aquarium classifications: tropical versus cold water . Most fish and plant species tolerate only a limited temperature range; tropical aquaria, with an average temperature of about 25 °C (77 °F), are much more common. Temperate or coldwater aquaria are for fish that are better suited to

1677-561: A peaceful life for the inhabitants of his territory. He achieved this by working closely with local elites and understanding the needs of the villagers, having grown up as the son of a poor peasant himself. Zhu's principles also proved beneficial for the economy of the controlled territory. In 1361, he began minting coins, established a monopoly on the sale of salt and tea, and started collecting traditional customs duties in 1362. These measures resulted in an increase in tax revenues, which were crucial for funding successful military campaigns. In

1806-433: A popular choice for many home and hobbyist aquarists for many years. Once silicone sealant became strong enough to ensure a long-term water-tight seal, it eliminated the need for a structural frame. In addition to lower cost, glass aquaria are more scratch resistant than acrylic. Although the price is one of the main considerations for aquarists when deciding which of these two types of aquaria to purchase, for very large tanks,

1935-524: A profound impact on the future emperor's life. He developed a deep understanding of the struggles faced by ordinary people, while harboring disdain for scholars who only gained knowledge from books. In 1352, he joined one of the rebel divisions. He quickly distinguished himself among the rebels and rose to lead his own army. In 1356, he conquered Nanjing and established it as his capital. He formed his own government, consisting of both generals and Confucian scholars, rejecting Mongol rule over China. He adopted

2064-515: A result, the generals became the dominant ruling class, surpassing the bureaucracy in power and influence. The officials had little political autonomy and simply carried out the emperor's orders and requests. This system mirrored the one established during the Yuan dynasty, with the ruling class of Mongols and Semu being replaced by families of distinguished military commanders. These families were often connected through kinship ties with each other and with

2193-453: A significant advantage over other rivals, but also increased his prestige among his own people. The fighting began when the Han army attacked Nanjing in 1360, but they were quickly defeated by Zhu. In 1361, the war spread to the Han province of Jiangxi, which changed hands multiple times. By the following year, Zhu had gained control of the province. In January 1363, Zhang Shicheng's army launched

2322-458: A small glass bowl, a few liters in volume, to immense public aquaria of thousands of liters. Specialized equipment maintains appropriate water quality and other characteristics suitable for the aquarium's residents. In 1369, the Hongwu Emperor of China established a porcelain company that produced large porcelain tubs for maintaining goldfish ; over time, people produced tubs that approached

2451-399: A small number of relatives who were appointed to important positions. In the unstable political climate, family ties were crucial for ensuring loyalty and reliability. The rivalry between Peng and Zhao escalated into a full-blown conflict. Guo was initially captured, but was later freed by his sons and Zhu, which only increased his reliance on Zhu. After Peng's death in 1353, Zhao emerged as

2580-405: A strong state and an active monarch. As an independent ruler, Zhu advocated for moderation in tax collection. However, other rebel leaders and his own generals prioritized military needs and often confiscated grain from peasants to feed their soldiers or prevent it from falling into the hands of their enemies. In contrast, Zhu placed great importance on maintaining orderly government and promoting

2709-464: A surprise attack on Anfeng, the residence of Song emperor Han Lin'er, resulting in the death of Liu Futong , the de facto leader of the regime. Despite being formally under the control of the Song government, Zhu offered his army to assist Han Lin'er, who was still highly respected among the troops. As a result, the powerless Han Lin'er was relocated to Chuzhou , located west of Nanjing on the opposite side of

2838-401: A tank by diluting effects from death or contamination events that push an aquarium away from equilibrium. The bigger the tank, the easier such a systemic shock is to absorb, because the effects of that event are diluted. For example, the death of the only fish in an 11-litre (3 US gal; 2 imp gal) tank causes dramatic changes in the system, while the death of that same fish in

2967-449: A tropical temperature and requires less capacity from an aquarium heater. Acrylic-soluble cements are used to directly fuse acrylic together. Acrylic allows for the formation of unusual shapes, such as the hexagonal tank. Acrylics are easier to scratch than glass, but unlike glass, scratches in acrylic can be polished out. Large aquaria might instead use stronger materials such as fiberglass -reinforced plastics . However, this material

3096-542: A villager from the right bank of the Huai River . His difficult upbringing never left his mind, and even as emperor, he held onto the ideal of a self-sufficient village life in peace, a dream that was unattainable in his youth. He made every effort to make this dream a reality for his subjects. The ultimate goal of the Hongwu Emperor's reforms was to achieve political stability for the state. All policies, institutions, and

3225-431: Is an important, although often overlooked, nutrient cycle. Sulfur, iron, and micronutrients also cycle through the system, entering as food and exiting as waste. Appropriate handling of the nitrogen cycle , along with supplying an adequately balanced food supply and considered biological loading, is enough to keep these other nutrient cycles in approximate equilibrium. An aquarium must be maintained regularly to ensure that

3354-436: Is frequently achieved via activated carbon , to filter medications, tannins , and/or other known impurities from the water. Reef aquaria under 100 litres (26 US gal; 22 imp gal) have a special place in the aquarium hobby; these aquaria, termed nano reefs (when used in reefkeeping), have a small water volume, under 40 litres (11 US gal; 9 imp gal). Practical limitations, most notably

3483-608: Is keeping them in a wall. Here the use of plywood is hidden by sinking the aquarium inside the wall. Putting insulation between the two helps with the insulation of a heated tank. Objects used for aquariums include: coffee tables, sinks, and even toilets. Another such example is the MacQuarium , an aquarium made from the shell of an Apple Macintosh computer . In recent years, elaborate custom-designed home aquariums costing hundreds of thousands of dollars have become status symbols—according to The New York Times , "among people of means,

3612-506: Is most often addressed through two filtration solutions: Activated carbon filters absorb nitrogen compounds and other toxins , while biological filters provide a medium designed to enhance bacterial colonization . Activated carbon and other substances, such as ammonia absorbing resins, stop working when their pores fill, so these components have to be replaced regularly. Hongwu Emperor The Hongwu Emperor (21 October 1328   – 24 June 1398), also known by his temple name as

3741-471: Is not transparent. Reinforced concrete is used for aquaria where weight and space are not factors. Concrete must be coated with a waterproof layer to prevent the water from breaking down the concrete, as well as preventing contamination of the water by the concrete. Plywood can also be used when building aquaria. The benefits of using plywood include: lower construction costs, less weight, and better insulation. A popular positioning choice for plywood aquaria

3870-626: Is one of the West Midlands ' most popular tourist attractions and welcomes hundreds of thousands of visitors every year. It was voted Aquarium of the Year and Warwickshire Family Attraction of the Year (despite not being in the current administrative county of Warwickshire) by the Good Britain Guide 2004. Aquarium The aquarium principle was fully developed in 1850 by the chemist Robert Warington , who explained that plants added to water in

3999-478: Is only a portion of the complete cycle: nitrogen must be added to the system (usually through food provided to the tank inhabitants), and nitrates accumulate in the water at the end of the process, or become bound in the biomass of plants. The aquarium keeper must remove water once nitrate concentrations grow, or remove plants which have grown from the nitrates. Hobbyist aquaria often do not have sufficient bacteria populations to adequately denitrify waste. This problem

4128-518: Is the most basic measure of water conditions. An aquarium may have freshwater (salinity below 500 parts per million), simulating a lake or river environment; brackish water (a salt level of 500 to 30,000 PPM), simulating environments lying between fresh and salt, such as estuaries ; and salt water or seawater (a salt level of 30,000 to 40,000 PPM), simulating an ocean environment. Rarely, higher salt concentrations are maintained in specialized tanks for raising brine organisms. Saltwater

4257-415: Is to have very small aquariums, termed mini aquariums (less than 150 litres or 40 gallons) or nano aquariums (less than 75 litres or 20 gallons). These can be either freshwater or saltwater, and are intended to display a tiny but self-contained ecosystem. The typical hobbyist aquarium includes a filtration system, an artificial lighting system, an air diffuser and pump, and a heater or chiller depending on

4386-499: Is toxic to fish in high concentrations. Another type of bacteria (genus Nitrospira ) converts nitrite into nitrate , a less toxic substance. ( Nitrobacter bacteria were previously believed to fill this role. While biologically they could theoretically fill the same niche as Nitrospira , it has recently been found that Nitrobacter are not present in detectable levels in established aquaria, while Nitrospira are plentiful.) However, commercial products sold as kits to "jump start"

4515-541: Is usually alkaline, while the pH ( alkalinity or acidity ) of fresh water varies more. Hardness measures overall dissolved mineral content; hard or soft water may be preferred. Hard water is usually alkaline, while soft water is usually neutral to acidic. Dissolved organic content and dissolved gases content are also important factors. Home aquarists typically use tap water supplied through their local water supply network to fill their tanks. Straight tap water cannot be used in localities that pipe chlorinated water. In

4644-607: The Emperor Taizu of Ming , personal name Zhu Yuanzhang , courtesy name Guorui , was the founding emperor of the Ming dynasty , reigning from 1368 to 1398. In the mid-14th century, China was plagued by epidemics, famines, and peasant uprisings during the rule of the Mongol Yuan dynasty . Zhu Yuanzhang, who lost his parents during this tumultuous time, was forced to survive by begging as an itinerant monk . This difficult upbringing had

4773-688: The Great Exhibition of 1851. In 1853, the aquarium craze was launched in England by Philip Henry Gosse who created and stocked the first public aquarium in the London Zoo which came to be known as the Fish House. Gosse coined the word "aquarium", opting for this term (instead of "aquatic vivarium" or "aqua-vivarium") in 1854 in his book The Aquariums: An Unveiling of the Wonders of the Deep Water . In this book, Gosse primarily discussed saltwater aquaria. In

4902-542: The Victorian era in the United Kingdom, a common design for the home aquarium was a glass front with the other sides made of wood (made watertight with a pitch coating). The bottom would be made of slate and heated from below. More advanced systems soon began to be introduced, along with tanks of glass in metal frames. During the latter half of the 19th century, a variety of aquarium designs were explored, such as hanging

5031-604: The aquascaping designs of Takashi Amano influencing fishkeepers to treat home aquariums as aesthetically pleasing compositions, rather than simply as a way of displaying fish specimens. In the United States, as of 1996, aquarium keeping is the second-most popular hobby after stamp collecting . In 1999, an estimated 9.6 million US households owned an aquarium. Figures from the 2005/2006 APPMA National Pet Owners Survey report that Americans own approximately 139 million freshwater fish and 9.6 million saltwater fish. Estimates of

5160-447: The gravel , or other substrate if the aquarium has one; however some manage to avoid this entirely by keeping it somewhat self-sufficient. A good habit is to remove the water being replaced by "vacuuming" the gravel with suitable implements, as this will eliminate uneaten foods and other residues that settle on the substrate . In many areas tap water is not considered to be safe for fish to live in because it contains chemicals that harm

5289-481: The nitrogen cycle or be removed by passing through zeolite . Ammonia is also produced through the decomposition of plant and animal matter, including fecal matter and other detritus . Nitrogen waste products become toxic to fish and other aquarium inhabitants at high concentrations. In the wild, the vast amount of water surrounding the fish dilutes ammonia and other waste materials. When fish are put into an aquarium, waste can quickly reach toxic concentrations in

5418-661: The weight of water (1 kilogram per litre (8.345 lb/U.S. gal; 10.022 lb/imp gal)) and internal water pressure (requiring thick glass siding) of a large aquarium, restrict most home aquaria to a maximum of around 1 cubic metre in volume (1000 L, weighing 1,000 kg or 2,200 lb ). Some aquarists, however, have constructed aquaria of many thousands of litres. Public aquariums and oceanariums designed for exhibition of large species or environments can be dramatically larger than any home aquarium. The Georgia Aquarium , for example, features an individual aquarium of 6,300,000 US gallons (24,000,000 L). A new trend

5547-429: The 1850s, the aquarium became a fad in the United Kingdom. Tank designs and techniques for maintaining water quality were developed by Warington, later cooperating with Gosse until his critical review of the tank water composition. Edward Edwards developed these glass-fronted aquaria in his 1858 patent for a "dark-water-chamber slope-back tank", with water slowly circulating to a reservoir beneath. Germans soon rivaled

5676-509: The 1960s, metal frames made marine aquaria almost impossible due to corrosion, but the development of tar and silicone sealant allowed the first all-glass aquaria made by Martin Horowitz in Los Angeles, CA. The frames remained, however, though purely for aesthetic reasons. Japan played an increasingly important role in shaping aquarium design in the latter part of the twentieth century, with

5805-627: The British in their interest. In 1854, an anonymous author had two articles published about the saltwater aquaria of the United Kingdom: Die Gartenlaube (The Garden House) entitled Der Ocean auf dem Tische (The Ocean on the Table). However, in 1856, Der See im Glase (The Lake in a Glass) was published, discussing freshwater aquaria, which were much easier to maintain in landlocked areas. In 1862 William Alford Lloyd , then bankrupt because of

5934-527: The Chief Military Commission was in charge of the army. However, under later emperors, the civil administration, which was the core of the government, became primarily focused on supporting the army financially and logistically. Initially, the provinces were under the control of the general, with the civil authorities also reporting to them. However, in the 1370s, the military's influence decreased as ministers were appointed to leadership positions in

6063-613: The Confucian belief that the ruler's moral example was the most important factor. The Hongwu Emperor also prioritized the safety of his people and the loyalty of his subordinates, demonstrating pragmatism and caution in military affairs. He maintained a disciplined army and made efforts to minimize the impact of war on civilians. Although the peak of his political system crumbled in a civil war shortly after his death, other results of his reforms , such as local and regional institutions for Ming state administration and self-government, as well as

6192-417: The Han's territories. Numerous Han prefectural and county commanders surrendered without resistance, and Huguang was pacified by General Xu Da by April 1365. By February 1365, Generals Chang Yuchun and Deng Yu had gained control over central and southern Jiangxi. This annexation of territories provided Zhu with a significant population advantage over its adversaries. The main threats to Zhu at this time were

6321-450: The Jinhua school, had a clear vision of a unified state governed by a small but efficient bureaucracy. They aimed to eliminate corruption, which was prevalent during the end of the Yuan dynasty. They believed that the state and its laws could be used to improve public morals and customs. While their motives may have differed from the emperor's, they shared a desire to bring about change through

6450-523: The Ming army, from his acquaintances who had already joined the rebels, and became their leader. Thanks to his abilities, he rose to prominence quickly, leading a 700-man squad by the spring of 1353 and becoming Guo's most trusted subordinate. Skilled in both military tactics and political maneuvering, he even married Guo's adopted daughter, surnamed Ma. A strong relationship developed between Lady Ma and Zhu, which would later give her great influence at court as empress. Unlike other leaders of his time, Zhu had

6579-566: The Ming, the local regime refused to submit. In response, General Fu Youde was ordered to lead an attack from the north in 1371. Simultaneously, Tang He and Liao Yongzhong advanced with a fleet up the Yangtze River. Although they initially faced resistance, they were able to push forward with the help of artillery and the enemy's decision to send part of their defenders north against the second army's successful advance. By September 1371, Sichuan had been conquered. This victory ensured stability in

6708-618: The Mongol warlord Köke Temür in northern China and Zhang Shicheng, who was based in Suzhou. Expansion of the army with former Han troops required a reorganization of the military. Therefore, in 1364, Zhu implemented the Weisuo system, which involved the formation of guards ( wei ) comprising 5,600 soldiers. These guards were further divided into 5 battalions ( qianhusuo ) of 1,120 soldiers each, with 10 companies ( baihusuo ) in each battalion. After 1364,

6837-456: The Nanchang garrison , led by Deng Yu ( 鄧兪 ), held out until early June 1363. In mid-August, Zhu's army and fleet finally set out from Nanjing with approximately 100,000 soldiers. The two fleets clashed on Lake Poyang on 29 August 1363, engaging in a four-day battle that resulted in the defeat of the Han fleet and the death of Chen Youliang. In 1364–1365, Zhu focused on conquering and absorbing

6966-459: The Yangtze River. However, the army remained stationed in the north until August 1363. The departure of Zhu's main forces to the north presented Chen with an opportunity to turn the tide of the war. He quickly raised an army of 300,000, outnumbering Zhu's remaining forces. Chen's plan was to capture Nanchang and then rally the local leaders in Jiangxi to join his cause and attack Nanjing. However,

7095-482: The addition of a commercially available mixture of salts and other minerals. Some aquarists modify water's alkalinity, hardness, or dissolved content of organics and gases, before adding it to their aquaria. This can be accomplished by additives, such as sodium bicarbonate, to raise pH. Some aquarists filter or purify their water through deionization or reverse osmosis prior to using it. In contrast, public aquaria with large water needs often locate themselves near

7224-548: The aquarium on a wall, mounting it as part of a window , or even combining it with a birdcage . Around 1908, the first mechanical aquarium air pump was invented, powered by running water, instead of electricity. The introduction of the air pump into the hobby is considered by several historians of the hobby to be a pivotal moment in its development. Aquaria became more widely popular as houses had an electricity supply after World War I . Electricity allowed artificial lighting, as well as aeration , filtration , and heating of

7353-505: The aquarium's inhabitants. Many aquaria incorporate a hood, containing the lights, to decrease evaporation and prevent fish from leaving the aquarium (and anything else from entering the aquarium). Combined biological and mechanical aquarium filtration systems are common. These either convert ammonia to nitrate (removing nitrogen at the expense of aquatic plants), or to sometimes remove phosphate . Filter media can house microbes that mediate nitrification . Filtration systems are sometimes

7482-491: The aquarium's inhabitants. Water movement can be controlled via aeration from air pumps, powerheads, and careful design of internal water flow (such as location of filtration system points of inflow and outflow). Of primary concern to the aquarist is management of the waste produced by an aquarium's inhabitants. Fish, invertebrates, fungi , and some bacteria excrete nitrogen waste in the form of ammonia (which converts to ammonium , in water) and must then either pass through

7611-586: The aquarium. According to the July issue of The North American Review of the same year, William Stimson may have owned some of the first functional aquaria, and had as many as seven or eight. The first aquarist society in the United States was founded in New York City in 1893, followed by others. The New York Aquarium Journal , first published in October 1876, is considered to be the world's first aquarium magazine. In

7740-506: The army was made up of 17 guards consisting of veterans who had previously served before 1363. The older veterans were demobilized, while the others were assigned to the garrison in Nanjing where they worked as military peasants, using their production to provide food for the army. Additional soldiers, who were reliable but had shorter periods of service, were acquired during the conquest of southern Anhui and central Zhejiang. They were stationed in

7869-497: The attacking troops, and the plan was executed with ease due to the attacking army's superiority. The ten-month siege of Suzhou began in December 1366. In January 1367, Han Lin'er drowned in the Yangtze River. As a result, Zhu's state of Wu officially declared its independence. A year later, in 1368, Zhu Yuanzhang proclaimed himself emperor and changed the name of the state. He followed the Mongol tradition of elevating titles and named

7998-581: The basics of Buddhism. In 1352, when the Mongol army burned down the monks' dwellings during the Red Turban Rebellion , Zhu joined one of the rebel divisions. The harsh taxation policies, famine, and catastrophic flooding in the Yellow River basin, caused by inadequate flood control measures, led to widespread opposition to the rule of the Mongol Yuan dynasty. This discontent was further fueled by

8127-515: The beginning of 1360, Zhu controlled the southwestern part of Jiangsu, all of Anhui south of the Yangtze River, and the inland of Zhejiang. By 1393, these territories had a population of 7.8 million. The domain (known as the Kingdom of Wu since 1363), led by Zhang Shicheng, had comparable power with a larger population but worse organization. Chen Youlang's state of Han had a similar situation. The state of Han , located west of Zhu's territory, included

8256-460: The behavior and survival of tank inhabitants. An aquarium can be placed on an aquarium stand. Because of the weight of the aquarium, a stand must be strong as well as level. A tank that is not level may distort, leak, or crack. These are often built with cabinets to allow storage, available in many styles to match room decor . Simple metal tank stands are also available. Most aquaria should be placed on polystyrene to cushion any irregularities on

8385-426: The border with Zhang's state was fortified on both sides and remained stable until 1366. In Zhejiang , from 1358 to 1359, he controlled four impoverished inland prefectures, while Zhang Shicheng held control over four prosperous northern coastal prefectures, and Fang Guozhen occupied the eastern coast of the province. In the summer of 1359, the Mongol warlord Chaghan Temur expelled Han Lin'er from Kaifeng . Han

8514-463: The captured prince Maidilibala to Mongolia. A favorite passage of the Hongwu Emperor from Daode jing ( The Way and Its Power ): Let the state be small and the people few: So that the people... So that the people... Though adjoining states be within sight of one another The Hongwu Emperor's public statements were filled with sympathy for the peasants and a deep distrust of the wealthy landowners and scholars. He often referred to himself as

8643-607: The central and eastern armies were ultimately defeated by the Mongols. These failures in 1372 shattered the Hongwu Emperor's dream of becoming the heir to the entire Yuan Empire, both in China and on the steppe. Furthermore, Japanese piracy increased and rebellions broke out in the provinces of Guangxi , Huguang , Sichuan, and Shaanxi. As a result, the Chinese forces in the north shifted their focus to defense, and two years later, they returned

8772-455: The centre announced as its newest attraction, a "Sensorama 4-D Cinema". In addition to 3-D viewing, the audience can be subjected to sensations such as wind, salt spray, and the smell the seaweed, or other sensations depending on the (sea-themed) film. In 2014 the centre opened a £2,000,000 'Penguin Ice Adventure' habitat that became home to a colony of gentoo penguins . During March 2020,

8901-622: The centre became home to a pair of northern sea otters , named Ozzy and Ola. They were the first and only sea otters to be displayed at any zoological collection in the UK and were rescued in Alaska . The centre has been featured in a number of documentaries, including the BBC 's 'Penguins on a plane: Great animal moves' and 'Shark'. Sir David Attenborough visited the centre in 2010 while filming his BBC2 series First Animals . The National Sea Life Centre Birmingham

9030-480: The city. After conquering it, he renamed the city Yingtian, which means "In response to Heaven". In May 1356, Han Lin'er appointed Zhu as the head of Jiangnan Province, one of the five provinces of the Song state. Guo's remaining son was chosen as his deputy. However, Zhu soon accused Guo's son of plotting against him and had him executed. This allowed Zhu to establish clear leadership and he immediately began to build his administration. However, he could not fully trust

9159-450: The concept of country administration from them and implemented it in the territory he controlled, eventually expanding it to the entire country. He gradually defeated rival rebel leaders, with the decisive moment being his victory over Chen Youliang in the Battle of Lake Poyang in 1363. In 1364, he declared himself King of Wu. In 1367, however, he still acknowledged his formal subordination to

9288-516: The craze in England being over, moved to Grindel Dammthor, Hamburg, to supervise the installation of the circulating system and tanks at the Hamburg Aquarium . During the 1870s, some of the first aquarist societies were appearing in Germany. The United States soon followed. Published in 1858, Henry D. Butler's The Family Aquarium was one of the first books written in the United States solely about

9417-433: The dominant leader in the region, leaving Guo and Zhu isolated. Zhao sent Guo to the east and Zhu with a small detachment to the south, hoping to divide them and be able to destroy them. However, contrary to Zhao's expectations, Zhu successfully occupied several counties and bolstered his army to 20,000 soldiers. Guo moved with Zhao's ten thousand men to join him. In the beginning of 1355, Zhu, Guo, and Zhang Shicheng , who

9546-481: The emperor met with his generals in the captured city of Kaifeng to confirm plans for the campaign. In mid-August, the Ming army resumed its march and reached Dadu (present-day Beijing ) in early September. They defeated the Mongol army outside the city and then occupied it, while the Yuan emperor Toghon Temür fled north to Shangdu . The city was renamed Beiping (Pacified North) by the Chinese. The campaign then continued with an attack on Shanxi . In January 1369,

9675-688: The empire "Great Ming" ( Da Ming ; 大明 ; 'Great Radiance'). He also renamed the upcoming "second year of the Wu era" as the "first year of the Hongwu era" ( 洪武 ; 'vastly martial'). In the autumn of 1367, Zhu's troops launched an attack against Fang Guozhen. By December of that year, they had successfully taken control of the entire coast. In November 1367, Hu Mei 's army, along with the fleets of Tang He and Liao Yongzhong, began their journey south. By February 1368, they had easily conquered Fujian, and by April 1368, they had also taken control of Guangdong. In July 1368, with

9804-466: The empire was Nanjing (Southern Capital), which was known as Yingtian until 1368. In the 1360s and 1370s, the capital underwent extensive construction. A workforce of 200,000 individuals surrounded the city with walls that were almost 26 km long, making them the longest in the world at the time. Additionally, an imperial palace and government quarter were built. In 1368, the emperor resided in Kaifeng during

9933-421: The enclosed environment unless the tank is cycled to remove waste. A well-balanced tank contains organisms that are able to metabolize the waste products of other aquarium residents, recreating a portion of the nitrogen cycle . Bacteria known as nitrifiers (genus Nitrosomonas ) metabolize nitrogen waste. Nitrifying bacteria capture ammonia from the water and metabolize it to produce nitrite . Nitrite

10062-451: The enemy could exploit the potential of the newly conquered territories. However, their offensive was repulsed in the spring of 1365. Before launching a final attack on the enemy's heartland, the Suzhou region, Zhu and his generals decided to first "cut off the wings" of Wu by occupying the territory north of the Yangtze and the Wu part of Zhejiang. Xu Da was appointed as the supreme commander of

10191-481: The eyes of the Yuan dynasty. Guo submitted to Peng, while his four colleagues submitted to Zhao. On 15 April 1352, Zhu Yuanzhang arrived in the city. Despite starting as a rank-and-file fighter, his exceptional leadership, decisiveness, warrior skills, and intelligence quickly gained him significant authority. Not only was Zhu known for his intelligence, but also for his unattractive appearance. He swiftly recruited 24 companions, who would eventually become generals in

10320-574: The financial and examination systems , proved to be resilient. The census, land registration and tax system, and the Weisuo military system all endured until the end of the dynasty. His descendants continued to rule over all of China until 1644, and the southern region for an additional seventeen years. Zhu Yuanzhang was born in 1328 in Zhongli ( 鍾離 ) village, located in Haozhou (present-day Fengyang , Anhui ). He

10449-552: The first person to create aquaria for experimenting with aquatic organisms. This experimentation lead to several discoveries, including the first direct evidence that argonauts , a marine cephalopod, create their own shells. In 1836, soon after his invention of the Wardian case , Dr. Nathaniel Bagshaw Ward proposed to use his tanks for tropical animals. In 1841 he did so, though only with aquatic plants and toy fish. However, he soon housed real animals. In 1838, Félix Dujardin noted owning

10578-416: The fish are kept healthy. Daily maintenance consists of checking the fish for signs of stress and disease . Also, aquarists must make sure that the water has a good quality and it is not cloudy or foamy and the temperature of the water is appropriate for the particular species of fish that live in the aquarium. Typical weekly maintenance includes changing around 10–30% or more of the water while cleaning

10707-594: The fish. Tap water from those areas must be treated with a suitable water conditioner, such as a product which removes chlorine and chloramine and neutralizes any heavy metals present. The water conditions must be checked both in the tank and in the replacement water, to make sure they are suitable for the species. The solute content of water is perhaps the most important aspect of water conditions, as total dissolved solids and other constituents dramatically impact basic water chemistry, and therefore how organisms interact with their environment. Salt content, or salinity ,

10836-520: The following four-year war, he drove out the Mongol armies loyal to the Yuan dynasty and unified the country. However, his attempt to conquer Mongolia ended in failure. During the thirty-year reign of the Hongwu Emperor, Ming China experienced significant growth and recovered from the effects of prolonged wars. The emperor had a strong understanding of the structure of society and believed in implementing reforms to improve institutions. This approach differed from

10965-425: The former Han territory, with field armies concentrated in Nanchang and Wuchang, and garrisons scattered across Jiangxi and Huguang. The remaining soldiers, mostly former Han soldiers, were joined by some veterans in the field armies sent to fight against the state of Wu under the leadership of Generals Xu Da and Chang Yuchun. After Chen Youliang's defeat, Zhu took on the title of King of Wu ( Wu wang ) starting from

11094-539: The future capital, named Zhongdu ( 中都 ; 'Central Capital'), began with grand plans. The area had been largely abandoned since the famine of the 1340s, so landless families from the south were resettled in Fengyang. However, in 1375, the emperor ultimately abandoned the idea of relocating the capital and the construction was halted. Upon ascending to the throne, the Hongwu Emperor appointed his wife as empress and his eldest son, Zhu Biao, as his heir. He surrounded himself with

11223-510: The future, as well as any changes to his laws. The compilation of the new code, known as the Great Ming Code , began in 1364. This code, which was heavily influenced by Confucian principles, was largely based on the old Tang Code of 653. The initial wording was agreed upon in 1367, and the final version was adopted in 1397. It remained unchanged until the fall of the empire, although additional provisions were later added. The capital of

11352-473: The glass panels attached with metal frames and sealed with putty. Metal-framed aquariums were still available until the mid-1960s, when the modern, silicone-sealed style replaced them. Acrylic aquariums first became available to the public in the 1970s. Laminated glass is sometimes used, which combines the advantages of both glass and acrylic. Today, most aquaria consist of glass panes bonded together by 100% silicone sealant, with plastic frames attached to

11481-536: The home by hobbyists . There are large public aquariums in many cities. Public aquariums keep fish and other aquatic animals in large tanks. A large aquarium may have otters , dolphins , sharks , penguins , seals , and whales . Many aquarium tanks also have plants. An aquarist owns fish or maintains an aquarium, typically constructed of glass or high-strength acrylic . Aquaria with flat walls are known as fish tanks or simply tanks, while those with rounded walls are known as fish bowls . Size can range from

11610-481: The imperial family. The administrative structure of the Ming dynasty was modeled after the Yuan model. The civil administration was led by the Central Secretariat , headed by two Grand Councilors who were informally known as Prime Ministers. This Secretariat was responsible for six ministries: Personnel , Revenue , Rites , War , Justice , and (Public) Works . The Censorate oversaw the administration, while

11739-542: The imperial title. In June, Li conquered Yingchang and Ajushiridara fled. However, his empress and son Maidilibala were captured along with more than 50,000 soldiers. The Mongolian ruler continued to flee until reaching Karakorum, where the remnants of Köke's army had also retreated. After successfully defeating the Mongols, the Ming government shifted its focus to the Xia state in Sichuan. Despite maintaining positive relations with

11868-536: The local Yuan commander, Chen Esen, who then surrendered to him. However, in September 1355, during an attempt to conquer Jiqing (present-day Nanjing), Chen Esen betrayed Guo Tianxu. In the ensuing battles, Guo Tianxu, Zhang Tianyu and Chen Esen himself were killed. In March 1356, Zhu once again marched on Jiqing. The new Mongol commander, Chen Zhaoxian ( 陳兆先 ), who was the nephew and successor of Chen Esen, surrendered with 36,000 men. In April 1356, Zhu successfully entered

11997-467: The loyalty of his generals. Until the victory at Lake Poyang in 1363, there were instances of betrayal and defection to the enemy. He was now in command of an army of 100,000 soldiers, which was divided into divisions or wings ( 翼 ; yi ). In Nanjing itself, there were eight divisions and one per prefecture. From 1355 to 1357, he launched attacks against Zhang Shicheng in the direction of Suzhou and successfully occupied southern Jiangxi ; after this,

12126-507: The main Red Turban leader, Han Lin'er , who claimed to be the successor of the Song dynasty . In early 1368, after successfully dominating southern and central China, he chose to rename his state. He decided on the name Da Ming , which translates to "Great Radiance", for his empire. Additionally, he designated Hongwu , meaning "Vastly Martial", as the name of the era and the motto of his reign. In

12255-415: The main army, led by Xu Da, captured Taiyuan , while Köke Temür retreated to Gansu . In the spring of 1369, Ming troops also began to occupy Shaanxi . The province was fully taken by September 1369, but border skirmishes with Köke Temür's troops persisted until 1370. In 1370, the Ming government launched a two-pronged attack on Mongolia. Generals Li Wenzhong and Feng Sheng led an attack from Beijing to

12384-482: The months of June–August and October–November, leading to the city being known as Beijing (Northern Capital). In 1369, the Hongwu Emperor proposed a debate on the relocation of the capital. In August, his suggestion to move the capital to Fengyang (then known as Linhuai), the emperor's hometown in northern Anhui , on the south bank of the Huai River, approximately 100 km north of Nanjing, was approved. Construction of

12513-678: The most complex component of home aquaria. Aquarium heaters combine a heating element with a thermostat , allowing the aquarist to regulate water temperature at a level above that of the surrounding air, whereas coolers and chillers (refrigeration devices) are for use anywhere, such as cold water aquaria, where the ambient room temperature is above the desired tank temperature. Thermometers used include glass alcohol thermometers, adhesive external plastic strip thermometers , and battery-powered LCD thermometers. In addition, some aquarists use air pumps attached to airstones or water pumps to increase water circulation and supply adequate gas exchange at

12642-686: The most popular biotopes are the freshwater habitats of the Amazon River , the Rio Negro River, the African rift lake environments of Lake Malawi and Lake Tanganyika , and saltwater coral reefs of Australia , the Red Sea , and the Caribbean Sea . The fish, plants, substrate, rocks, wood, coral, and any other component of the display should completely match that of the local natural environment. It can be

12771-477: The new year (4 February) of 1364, which was the same title used by Zhang Shicheng since October 1363. Despite this, he still acknowledged his subordinate status to emperor Han Lin'er and used the Song era of Longfeng as long as Han was alive. However, he ran his own administration, following the model of the Yuan dynasty. In 1365–67, Zhu conquered the Zhang's state of Wu. Zhang attempted to attack in late 1364, before

12900-533: The nitrogen cycle often still contain Nitrobacter . Aquatic plants also eliminate nitrogen waste by metabolizing ammonia and nitrate. When plants metabolize nitrogen compounds, they remove nitrogen from the water by using it to build biomass that decays more slowly than ammonia-driven plankton already dissolved in the water. Some hobbyists also use "anoxic filtration," which relies on bacteria that live in low-oxygen environments. The nitrogen cycle in an aquarium

13029-551: The north, while Xu Da attacked from Xi'an against Köke Temür. In early May 1370, Köke Temür was defeated and fled to Karakorum . The Ming forces captured over 84,000 of his troops and continued to advance westward along the Yellow River. At the same time, Li's forces advanced to Shangdu, where the Yuan emperor Toghon Temür retreated further north to Yingchang and died in May 1370. His twenty-three-year-old son Ayushiridara then assumed

13158-480: The numbers of fish kept in aquaria in Germany suggest at least 36 million. The hobby has the strongest following in Europe, Asia, and North America. In the United States, 40% of aquarists maintain two or more tanks. Over time, there has been an increasing appreciation of the usefulness of access to an aquarium to provide potential stress reduction and improvement of mood in people observing aquatic life. According to

13287-410: The past, it was possible to "condition" the water by simply letting the water stand for a day or two, which allows the chlorine time to dissipate. However, chloramine is now used more often and does not leave the water as readily. Water conditioners formulated to remove chlorine or chloramine are often all that is needed to make the water ready for aquarium use. Brackish or saltwater aquaria require

13416-632: The post of governor of Jiangxi province. The ideology of the Red Turbans did not resonate with Zhu. Instead of trying to establish a new intellectual elite based on the Manichean-Buddhist beliefs of the White Lotus , he chose to collaborate with Confucian intellectuals. This shift in approach transformed him from a leader of a popular sectarian uprising to the leader of a political movement seeking traditional legitimacy. Nevertheless, he still relied on

13545-486: The presence of Taoist and Buddhist secret societies and sects, with the most prominent being the White Lotus society. In 1351, a rebellion known as the Red Turban Rebellion erupted and quickly spread throughout northern China. Despite the initial disorganization of the Mongol troops, they were able to launch a counteroffensive and advance along the Grand Canal . In October 1352, the Mongols captured Xuzhou , causing

13674-428: The price difference tends to disappear. Acrylic aquaria are now the primary competitor with glass. Prior to the invention of UV stabilization , early acrylic aquaria discolored over time with exposure to light; this is no longer the case. Acrylic is generally stronger than glass, weighs less, and provides a certain amount of temperature insulation. In colder climates or environments, it is easier to achieve and maintain

13803-575: The provinces of Jiangxi and Hubei . Zhang, based in Suzhou , controlled the lower reaches of the Yangtze, from the eastern borders of Zhu's dominions to the sea. While Zhu, Zhang, and Chen divided up the Yangtze River Basin, the rest of southern and central China was largely under the control of "one-province" regimes. Fang Guozhen controlled the eastern Chinese coast, Ming Yuzhen ruled in Sichuan , and

13932-496: The rebel Song emperor Han Lin'er appointed Guo's eldest son, Guo Tianxu, as his successor. Guo's brother-in-law, Zhang Tianyu, was chosen as the first deputy of the new commander, with Zhu as the second deputy. In order to cross the Yangtze River, the Hezhou rebels required a fleet, which they acquired in July 1355 when a group of rebels from Chao Lake arrived. They successfully crossed the river that same month. Zhu immediately defeated

14061-407: The rebel commanders Peng Da and Zhao Yunyong to flee south to Haozhou. In Haozhou, the Yuan dynasty's power fell in the spring of 1352. Guo Zixing , Sun Deyai, and three other leaders, with the support of the local elite, organized the army and took control in order to establish order in the city and its surrounding areas. The arrival of Peng and Zhao was seen as a clear connection to the rebels in

14190-460: The reinforcement of Yang Jing 's army from Huguang, Guangxi province was also occupied. At the same time as the southern campaign, Zhu sent a 250,000-strong army, led by Xu Da and Chang Yuchun, to conquer the North China Plain. By March 1368, both land and naval forces had successfully captured Shandong. In May, Henan was also occupied. A pause was taken for agricultural work, during which

14319-532: The research of having an aquarium is many health benefits like reduce stress, blood pressure and heart rate improvement, better quality sleep , reduce anxiety and pain , therapy of excited children, Alzheimer's therapy and improve productivity . The first modern aquarium made of glass was developed in the 19th century by Robert Warrington. During the Victorian age , glass aquariums commonly had slate or steel bottoms, which allowed them to be heated underneath by an open-flame heat source. These aquariums had

14448-482: The shape of modern fish bowls. Leonhard Baldner , who wrote Vogel-, Fisch- und Tierbuch (Bird, Fish, and Animal Book) in 1666, maintained weather loaches and newts . It is sometimes held that the aquarium was invented by the Romans, who are said to have kept sea barbels in marble-and-glass tanks, but scholars doubt the veracity of this. In 1832, Jeanne Villepreux-Power , a pioneering French marine biologist, became

14577-575: The social and economic structure of society were designed to serve this purpose. The chaos and foreign rule that led to the establishment of a new dynasty only reinforced his determination to maintain order. The emperor was meticulous in his efforts to establish a new society after the fall of the Yuan dynasty. He was a dynamic and innovative legislator, constantly issuing, revising, and modifying laws throughout his reign. However, these frequent changes sometimes sparked protests from officials. The emperor's legislation focused on four main themes. The first

14706-650: The southwestern border for the next ten years, until the pro-Mongol Yunnan was conquered in 1381-1382. In 1372, the emperor launched a massive attack on Mongolia, with Xu Da leading a 150,000-strong army from Shanxi through the Gobi to Karakorum. In the west, Feng Sheng was assigned to conquer the western part of the Gansu Corridor with 50,000 cavalrymen, while Li Wenzhong was tasked with attacking eastern Mongolia and Manchuria with another 50,000 soldiers. Although Feng Sheng's forces were able to successfully complete their mission,

14835-561: The support of his officers who shared his devotion to the teachings of the White Lotus. In 1354, he began working with Li Shanchang , a landowner from Dingyuan County, the first county conquered by Zhu. Li Shanchang was responsible for running the civil administration, and as Zhu conquered more cities, he recruited more scholars to join his cause. After repeated requests from Zhu in 1360, a group of prominent scholars, led by Song Lian and Liu Ji , joined his service. These scholars, known as

14964-399: The tank itself. The tank has no sharp angles around its sides and keeps the housed animals away from plumbing. Water moving into the tank gives a gentle flow that keeps the inhabitants suspended. Water leaves the tank through a screen which prevents animals from being drawn into the pump intake or overflow line. There are several types of kreisel tanks. In a true kreisel, a circular tank has

15093-450: The territories he conquered. However, Zhu feared the advance of the Yuan troops in the southern direction, all the way to Nanjing. As a result, he proposed cooperation with Chaghan Temur. After Chaghan Temur's army was unable to make progress in Shandong and he was murdered in the summer of 1362, the threat from the Yuan side disappeared. As a result, Zhu rejected the Yuan government's offer of

15222-406: The trio of Yuan loyalists ( Chen Youding , He Zhen , and Basalawarmi ) controlled Fujian , Guangdong , and Yunnan . These provincial regimes were unable to threaten the "big three", but were strong in defense. The war between Zhu's Jiangnan and Chen Youliang's Han state from 1360 to 1363 had a devastating impact on the balance of power in the Yangtze River Basin. This conflict not only gave Zhu

15351-579: The underlying surface or the bottom of the tank itself that may cause cracks. However, some tanks have an underframe making this unnecessary. Another important consideration for aquariums is their electrical usage. Water is expensive to keep heated, along with the lights that many aquariums, especially those with live plants have. New aquarists should also pay close attention to their electrical setup for their aquarium, taking care to set up power connections with drip loops to prevent water from getting to outlets. Large volumes of water enable more stability in

15480-580: The upper and lower edges for decoration. The glass aquarium is standard for sizes up to about 1,000 litres (260 US gal; 220 imp gal). However, glass is brittle and has very little give before fracturing, though generally the sealant fails first. Aquaria are made in a variety of shapes, such as cuboid , hexagonal , angled to fit in a corner (L-shaped), and bow-front (the front side curves outwards). Fish bowls are generally either made of plastic or glass, and are either spherical or some other round configuration in shape. Glass aquaria have been

15609-400: The water surface. Wave-making devices have also been constructed to provide wave action. An aquarium's physical characteristics form another aspect of aquarium design. Size, lighting conditions, density of floating and rooted plants, placement of bog-wood , creation of caves or overhangs, type of substrate , and other factors (including an aquarium's positioning within a room) can all affect

15738-611: The water. Initially, amateur aquarists kept native fish (with the exception of goldfish); the availability of exotic species from overseas further increased the popularity of the aquarium. Jugs made from a variety of materials were used to import fish from overseas, with a bicycle foot pump for aeration. Plastic shipping bags were introduced in the 1950s, making it easier to ship fish. The eventual availability of air freight allowed fish to be successfully imported from distant regions. Popular publications started by Herbert R. Axelrod influenced many more hobbyists to start keeping fish. In

15867-428: The world, the centre describes itself as a place that 'transports visitors into an underwater world of discovery'. 'Breed, Rescue and Protect' conservation projects are undertaken by aquarium staff, including an extensive seahorse breeding programme, with many species of newly reared seahorses in tanks viewable by visitors. In other displays, it has a green sea turtles , sharks , sting rays , and otters . In 2009,

15996-412: Was a broad desire to restore order and morality in society. The second was the regulation of the bureaucracy, including disciplining followers and managing the government. The third was the removal of corrupt and unreliable officials. Finally, the emperor also sought to resist the natural decline that comes with time. As the patriarch of the family, he aimed to prevent the decay of society and the dynasty in

16125-548: Was designed by Sir Norman Foster . It is located alongside the Birmingham Canal Navigations Main Line Canal by Old Turn Junction and opposite Arena Birmingham . It opened on 5 July 1996, at which time it was the only inland sea life centre in the UK. In the Victorian era , the site was the location of two canal basins in Oozells Street Wharf. Housing over 2,000 creatures from around

16254-497: Was fully developed by Warington, explaining that plants added to water in a container would give off enough oxygen to support animals, so long as their numbers do not grow too large. He published his findings in 1850 in the Chemical Society's journal . The keeping of fish in an aquarium became a popular hobby and spread quickly. In the United Kingdom, it became popular after ornate aquaria in cast-iron frames were featured at

16383-550: Was left with only a few hundred soldiers, but as Chaghan Temur focused on conquering Shandong , Han's group was able to survive in Anfeng, a prefectural city in the west of Anhui. After the retreat from Kaifeng, the Song government's power weakened rapidly. Apart from Zhu Yuanzhang's effectively independent Jiangnan, no Song province survived 1362. In 1361, Han Lin'er appointed Zhu as the Duke of Wu ( Wu Guogong ) and recognized his rule in all

16512-479: Was located further east, made the decision to leave the war-torn territories and cross the Yangtze River to the prosperous southern regions that had not yet been affected by the war. However, a dispute arose between Guo and Zhu over the city of Hezhou, situated on the banks of the Yangtze River. Zhu even formed an alliance with Sun Deyai, Guo's old enemy. Before the conflict could escalate, Guo died. Following this,

16641-401: Was the youngest of four sons in a poor peasant family. He was given the name Zhu Chongba ( 朱重八 ) at birth, but later used the name Zhu Xingzong ( 朱興宗 ) in adulthood. After joining the rebels, he went by the name Zhu Yuanzhang. His father, Zhu Wusi , lived in Nanjing but fled to the countryside to avoid tax collectors. His paternal grandfather was a gold miner, and his maternal grandfather was
