117-571: Bishan Depot or ( Chinese : 碧山车厂 ) is a depot located on the Mass Rapid Transit in Bishan , Singapore . It was completed in 1986 by American architect Vikas M. Gore and the 12,000 square metres maintenance area at cost of S$ 300 million. The depot comprises a storage yard with a capacity of 59 trains and has an area of 300,000 m. The depot also houses a central maintenance facility with train overhaul facilities and supply of trains travelling on
234-544: A | and single-storey | ɑ | forms both representing the Latin letter ⟨ A ⟩ . Variants also emerge for aesthetic reasons, to make handwriting easier, or to correct what the writer perceives to be errors in a character's form. Individual components may be replaced with visually, phonetically, or semantically similar alternatives. The boundary between character structure and style—and thus whether forms represent different characters, or are merely variants of

Technologies invented since the 19th century allowing for wider use of characters include telegraph codes and typewriters , as well as input methods and text encodings on computers. Chinese characters are accepted as representing one of four independent inventions of writing in human history. In each instance, writing evolved from
468-416: A character's meaning. Examples of phono-semantic compounds include 河 ( hé ; 'river'), 湖 ( hú ; 'lake'), 流 ( liú ; 'stream'), 沖 ( chōng ; 'surge'), and 滑 ( huá ; 'slippery'). Each of these characters have three short strokes on their left-hand side: 氵 , a simplified combining form of ⽔ 'WATER' . This component serves
585-443: A component—either a character or a sub-component called a radical —usually involves either a reduction in its total number of strokes , or an apparent streamlining of which strokes are chosen in what places—for example, the ⼓ ' WRAP ' radical used in the traditional character 沒 is simplified to ⼏ ' TABLE ' to form the simplified character 没 . By systematically simplifying radicals, large swaths of
702-434: A conversion table. While exercising such derivation, the following rules should be observed: Sample Derivations : The Series One List of Variant Characters reduces the number of total standard characters. First, amongst each set of variant characters sharing identical pronunciation and meaning, one character (usually the simplest in form) is elevated to the standard character set, and the rest are made obsolete. Then amongst

The Shang king would communicate with his ancestors by means of scapulimancy , inquiring about subjects such as the royal family, military success, and the weather. Inscriptions were made in the divination material itself before and after it had been cracked by exposure to heat; they generally include a record of the questions posed, as well as
936-407: A few revised forms, and was implemented for official use by China's State Council on 5 June 2013. In Chinese, simplified characters are referred to by their official name 简化字 ; jiǎnhuàzì , or colloquially as 简体字 ; jiǎntǐzì . The latter term refers broadly to all character variants featuring simplifications of character form or structure, a practice which has always been present as
1053-690: A given position in the compound. Components within a character may serve a specific function: phonetic components provide a hint for the character's pronunciation, and semantic components indicate some element of the character's meaning. Components that serve neither function may be classified as pure signs with no particular meaning, other than their presence distinguishing one character from another. A straightforward structural classification scheme may consist of three pure classes of semantographs , phonographs and signs —having only semantic, phonetic, and form components respectively, as well as classes corresponding to each combination of component types. Of
1170-558: A language. Specifically, characters represent the smallest units of meaning in a language, which are referred to as morphemes . Morphemes in Chinese—and therefore the characters used to write them—are nearly always a single syllable in length. In some special cases, characters may denote non-morphemic syllables as well; due to this, written Chinese is often characterized as morphosyllabic . Logographs may be contrasted with letters in an alphabet , which generally represent phonemes ,
1287-406: A line, and later evolved into their present forms with less potential for graphical ambiguity in context. More complex indicatives include 凸 ('convex'), 凹 ('concave'), and 平 ('flat and level'). Compound ideographs ( 会意 ; 會意 ; huìyì )—also called logical aggregates , associative idea characters , or syssemantographs —combine other characters to convey

#17330853645551404-542: A mature form, also called 八分 ( bāfēn ). Bamboo slips discovered during the late 20th century point to this maturation being completed during the reign of Emperor Wu of Han ( r. 141–87 BCE ). This process, called libian ( 隶变 ; 隸變 ), involved character forms being mutated and simplified, with many components being consolidated, substituted, or omitted. In turn, the components themselves were regularized to use fewer, straighter, and more well-defined strokes. The resulting clerical forms largely lacked any of
1521-419: A model first popularized in the 2nd-century Shuowen Jiezi dictionary. More recent models have analysed the methods used to create characters, how characters are structured, and how they function in a given writing system. Most characters can be analysed structurally as compounds made of smaller components ( 部件 ; bùjiàn ), which are often independent characters in their own right, adjusted to occupy
1638-685: A new, synthetic meaning. A canonical example is 明 ('bright'), interpreted as the juxtaposition of the two brightest objects in the sky: ⽇ 'SUN' and ⽉ 'MOON' , together expressing their shared quality of brightness. Other examples include 休 ('rest'), composed of pictographs ⼈ 'MAN' and ⽊ 'TREE' , and 好 ('good'), composed of ⼥ 'WOMAN' and ⼦ 'CHILD' . Many traditional examples of compound ideographs are now believed to have actually originated as phono-semantic compounds, made obscure by subsequent changes in pronunciation. For example,
1755-599: A newly coined phono-semantic compound : Removing radicals Only retaining single radicals Replacing with ancient forms or variants : Adopting ancient vulgar variants : Readopting abandoned phonetic-loan characters : Copying and modifying another traditional character : Based on 132 characters and 14 components listed in Chart 2 of the Complete List , the 1,753 derived characters found in Chart 3 can be created by systematically simplifying components using Chart 2 as
1872-568: A part of the Chinese writing system. The official name tends to refer to the specific, systematic set published by the Chinese government, which includes not only simplifications of individual characters, but also a substantial reduction in the total number of characters through the merger of formerly distinct forms. According to Chinese palaeographer Qiu Xigui , the broadest trend in the evolution of Chinese characters over their history has been simplification, both in graphical shape ( 字形 ; zìxíng ),
1989-719: A semantic component. Pictographs have often been extended from their original meanings to take on additional layers of metaphor and synecdoche , which sometimes displace the character's original sense. When this process results in excessive ambiguity between distinct senses written with the same character, it is usually resolved by new compounds being derived to represent particular senses. Indicatives ( 指事 ; zhǐshì ), also called simple ideographs or self-explanatory characters , are visual representations of abstract concepts that lack any tangible form. Examples include 上 ('up') and 下 ('down')—these characters were originally written as dots placed above and below
2106-563: A semantic function in each example, indicating the character has some meaning related to water. The remainder of each character is its phonetic component: 湖 ( hú ) is pronounced identically to 胡 ( hú ) in Standard Chinese, 河 ( hé ) is pronounced similarly to 可 ( kě ), and 沖 ( chōng ) is pronounced similarly to 中 ( zhōng ). The phonetic components of most compounds may only provide an approximate pronunciation, even before subsequent sound shifts in
2223-429: A stylus in clay moulds used to cast ritual bronzes . Characters have also been incised into stone, or written in ink onto slips of silk, wood, and bamboo. The invention of paper for use as a writing medium occurred during the 1st century CE, and is traditionally credited to Cai Lun ( d. 121 CE ). There are numerous styles, or scripts ( 书 ; 書 ; shū ) in which characters can be written, including
2340-540: A system using two distinct types of ideographs . Ideographs could either be pictographs visually depicting objects or concepts, or fixed signs representing concepts only by shared convention. These systems are classified as proto-writing , because the techniques they used were insufficient to carry the meaning of spoken language by themselves. Various innovations were required for Chinese characters to emerge from proto-writing. Firstly, pictographs became distinct from simple pictures in use and appearance: for example,
2457-540: A time and without indicating any greater context. Qiu concludes, "We simply possess no basis for saying that they were already being used to record language." A historical connection with the symbols used by the late Neolithic Dawenkou culture ( c. 4300 – c. 2600 BCE ) in Shandong has been deemed possible by palaeographers, with Qiu concluding that they "cannot be definitively treated as primitive writing, nevertheless they are symbols which resemble most

On 15 July 2016, local and Australian media reported that between April and July 2015, two Americans Jim Harper and Danielle Bremner, posted a series of vandalism videos online under the pseudonyms Utah and Ether , with one video showing them committing the act at Bishan depot. Harper was arrested and jailed 6-months in May in Melbourne, Australia , while his partner
2691-811: A transitional form between clerical and regular script which remained in use through the Three Kingdoms period (220–280 CE) and beyond. Cursive script ( 草书 ; 草書 ; cǎoshū ) was in use as early as 24 BCE, synthesizing elements of the vulgar writing that had originated in Qin with flowing cursive brushwork. By the Jin dynasty (266–420), the Han cursive style became known as 章草 ( zhāngcǎo ; 'orderly cursive'), sometimes known in English as 'clerical cursive', 'ancient cursive', or 'draft cursive'. Some attribute this name to
2808-510: A village near Anyang in Henan —discovered to be the site of Yin , the final Shang capital—which was excavated by a team led by Li Ji (1896–1979) from the Academia Sinica between 1928 and 1937. To date, over 150 000 oracle bone fragments have been found. Oracle bone inscriptions recorded divinations undertaken to communicate with the spirits of royal ancestors. The inscriptions range from
2925-481: A well-developed writing system, which suggests an initial emergence predating the late 2nd millennium BCE. Although written Chinese is first attested in official divinations, it is widely believed that writing was also used for other purposes during the Shang, but that the media used in other contexts—likely bamboo and wooden slips —were less durable than bronzes or oracle bones, and have not been preserved. As early as
3042-414: A word is used to indicate a different word with a similar pronunciation, depending on context. This allowed for words that lacked a plausible pictographic representation to be written down for the first time. This technique preempted more sophisticated methods of character creation that would further expand the lexicon. The process whereby writing emerged from proto-writing took place over a long period; when
3159-440: Is actually more complex than eliminated ones. An example is the character 搾 which is eliminated in favor of the variant form 榨 . The 扌 'HAND' with three strokes on the left of the eliminated 搾 is now seen as more complex, appearing as the ⽊ 'TREE' radical 木 , with four strokes, in the chosen variant 榨 . Not all characters standardised in the simplified set consist of fewer strokes. For instance,

Merging homophonous characters: Adapting cursive shapes ( 草書楷化 ): Replacing a component with a simple arbitrary symbol (such as 又 and 乂 ): Omitting entire components : Omitting components, then applying further alterations : Structural changes that preserve the basic shape Replacing the phonetic component of phono-semantic compounds : Replacing an uncommon phonetic component : Replacing entirely with
3393-474: Is given by Xu as 轉注 ( zhuǎnzhù ; 'reversed and refocused'); however, its definition is unclear, and it is generally disregarded by modern scholars. Modern scholars agree that the theory presented in the Shuowen Jiezi is problematic, failing to fully capture the nature of Chinese writing, both in the present, as well as at the time Xu was writing. Traditional Chinese lexicography as embodied in
3510-399: Is not required, and character forms may be accentuated to evoke a variety of aesthetic effects. Traditional ideals of calligraphic beauty often tie into broader philosophical concepts native to East Asia. For example, aesthetics can be conceptualized using the framework of yin and yang , where the extremes of any number of mutually reinforcing dualities are balanced by the calligrapher—such as
3627-809: Is now discouraged. A State Language Commission official cited "oversimplification" as the reason for restoring some characters. The language authority declared an open comment period until 31 August 2009, for feedback from the public. In 2013, the List of Commonly Used Standard Chinese Characters was published as a revision of the 1988 lists; it included a total of 8105 characters. It included 45 newly recognized standard characters that were previously considered variant forms, as well as official approval of 226 characters that had been simplified by analogy and had seen wide use but were not explicitly given in previous lists or documents. Singapore underwent three successive rounds of character simplification , eventually arriving at

Police reports were made in the early hours of the morning when trains were being dispatched from the depot. A third case of vandalism took place on 8 November 2014 when two Germans , Andreas Von Knorre and Elton Hinz, spraypainted a cabin on a C151 train after breaking into the depot. They were each sentenced to nine months jail and given three strokes of
3978-563: Is referred to as the " big seal script ". The traditional narrative, as also attested in the Shuowen Jiezi dictionary ( c. 100 AD ), is that the Qin small seal script that would later be imposed across China was originally derived from the Zhou big seal script with few modifications. However, the body of epigraphic evidence comparing the character forms used by scribes gives no indication of any real consolidation in character forms prior to
4095-457: Is regularly done with corporate brand names: for example, Coca-Cola 's Chinese name is 可口可乐 ; 可口可樂 ( Kěkǒu Kělè ; 'delicious enjoyable'). Some characters and components are pure signs , whose meaning merely derives from their having a fixed and distinct form. Basic examples of pure signs are found with the numerals beyond four, e.g. 五 ('five') and 八 ('eight'), whose forms do not give visual hints to
4212-540: Is used instead of 叠 in regions using traditional characters. The Chinese government stated that it wished to keep Chinese orthography stable. The Chart of Generally Utilized Characters of Modern Chinese was published in 1988 and included 7000 simplified and unsimplified characters. Of these, half were also included in the revised List of Commonly Used Characters in Modern Chinese , which specified 2500 common characters and 1000 less common characters. In 2009,
4329-446: The I ;Ching . According to one tradition, Chinese characters were invented during the 3rd millennium BCE by Cangjie , a scribe of the legendary Yellow Emperor . Cangjie is said to have invented symbols called 字 ( zì ) due to his frustration with the limitations of knotting, taking inspiration from his study of the tracks of animals, landscapes, and the stars in the sky. On
4446-548: The ⼑ 'KNIFE' component appears as 刂 on the right side of characters, but as ⺈ at the top of characters. The order in which components are drawn within a character is fixed. The order in which the strokes of a component are drawn is also largely fixed, but may vary according to several different standards. This is summed up in practice with a few rules of thumb, including that characters are generally assembled from left to right, then from top to bottom, with "enclosing" components started before, then closed after,
4563-646: The 3500 characters that are frequently used in Standard Chinese, pure semantographs are estimated to be the rarest, accounting for about 5% of the lexicon, followed by pure signs with 18%, and semantic–form and phonetic–form compounds together accounting for 19%. The remaining 58% are phono-semantic compounds. The Chinese palaeographer Qiu Xigui ( b. 1935 ) presents three principles of character function adapted from earlier proposals by Tang Lan [ zh ] (1901–1979) and Chen Mengjia (1911–1966), with semantographs describing all characters whose forms are wholly related to their meaning, regardless of

Their mass standardization during the 20th century was part of an initiative by the People's Republic of China (PRC) to promote literacy, and their use in ordinary circumstances on the mainland has been encouraged by the Chinese government since the 1950s. They are the official forms used in mainland China and Singapore , while traditional characters are officially used in Hong Kong , Macau , and Taiwan . Simplification of
4797-753: The Ming (1368–1644) and Qing dynasties (1644–1912) led to considerable standardization in character forms, which prefigured later script reforms during the 20th century. This print orthography , exemplified by the 1716 Kangxi Dictionary , was later dubbed the jiu zixing ('old character shapes'). Printed Chinese characters may use different typefaces , of which there are four broad classes in use: Before computers became ubiquitous, earlier electro-mechanical communications devices like telegraphs and typewriters were originally designed for use with alphabets, often by means of alphabetic text encodings like Morse code and ASCII .

Moreover, several categories are considered to be ill-defined: for example, it is unclear whether characters like 大 ('large') should be classified as pictographs or indicatives. However, awareness of the 'six writings' model has remained a common component of character literacy, and often serves as a tool for students memorizing characters. The broadest trend in

Xu based most of his analysis on examples of Qin seal script that were written down several centuries before his time—these were usually the oldest specimens available to him, though he stated he was aware of the existence of even older forms. The first five categories are pictographs, indicatives, compound ideographs, phono-semantic compounds, and loangraphs. The sixth category
5382-507: The Sinosphere . In Japanese , Korean , and Vietnamese , Chinese characters are known as kanji , hanja , and chữ Hán respectively.

For example, each character in the name 加拿大 ( Jiānádà ; 'Canada') is often used as a loangraph for its respective syllable. However, the barrier between a character's pronunciation and meaning is never total: when transcribing into Chinese, loangraphs are often chosen deliberately as to create certain connotations. This

This oracle bone script ( 甲骨文 ; jiǎgǔwén ) was first documented in 1899, after specimens were discovered being sold as "dragon bones" for medicinal purposes, with the symbols carved into them identified as early character forms. By 1928, the source of the bones had been traced to

These differences in technique generally resulted in character forms that were less angular in appearance than their oracle bone script counterparts. Study of these bronze inscriptions has revealed that

Western influence also resulted in the generalized use of punctuation being widely adopted in print during the 19th and 20th centuries. Prior to this, the context of a passage was considered adequate to guide readers; this was enabled by characters being easier than alphabets to read when written scriptio continua , due to their more discretized shapes. The earliest attested Chinese characters were carved into bone, or marked using

The oldest attested Chinese writing comprises a body of inscriptions produced during the Late Shang period ( c. 1250 – 1050 BCE), with the very earliest examples from the reign of Wu Ding dated between 1250 and 1200 BCE. Many of these inscriptions were made on oracle bones —usually either ox scapulae or turtle plastrons—and recorded official divinations carried out by

Ultimately, 明 became the character's standard form. From the earliest inscriptions until the 20th century, texts were generally laid out vertically—with characters written from top to bottom in columns, arranged from right to left. Word boundaries are generally not indicated with spaces . A horizontal writing direction—with characters written from left to right in rows, arranged from top to bottom—only became predominant in

Collections of graphs and pictures have been discovered at the sites of several Neolithic settlements throughout the Yellow River valley, including Jiahu ( c. 6500 BCE ), Dadiwan and Damaidi (6th millennium BCE), and Banpo (5th millennium BCE). Symbols at each site were inscribed or drawn onto artefacts, appearing one at
8658-417: The distinct process of semantic extension, where a word acquires additional senses, which often remain written with the same character. As both processes often result in a single character form being used to write several distinct meanings, loangraphs are often misidentified as being the result of semantic extension, and vice versa. Loangraphs are also used to write words borrowed from other languages, such as
8775-519: The distinct units of sound used by speakers of a language. Despite their origins in picture-writing, Chinese characters are no longer ideographs capable of representing ideas directly; their comprehension relies on the reader's knowledge of the particular language being written. The areas where Chinese characters were historically used—sometimes collectively termed the Sinosphere —have a long tradition of lexicography attempting to explain and refine their use; for most of history, analysis revolved around
8892-439: The duality between strokes made quickly or slowly, between applying ink heavily or lightly, between characters written with symmetrical or asymmetrical forms, and between characters representing concrete or abstract concepts. Woodblock printing was invented in China between the 6th and 9th centuries, followed by the invention of moveable type by Bi Sheng (972–1051) during the 11th century. The increasing use of print during
9009-472: The early 20th century. In 1909, the educator and linguist Lufei Kui formally proposed the use of simplified characters in education for the first time. Over the following years—marked by the 1911 Xinhai Revolution that toppled the Qing dynasty , followed by growing social and political discontent that further erupted into the 1919 May Fourth Movement —many anti-imperialist intellectuals throughout China began to see
9126-504: The evolution of Chinese characters over their history has been simplification, both in graphical shape ( 字形 ; zìxíng ), the "external appearances of individual graphs", and in graphical form ( 字体 ; 字體 ; zìtǐ ), "overall changes in the distinguishing features of graphic[al] shape and calligraphic style, [...] in most cases refer[ring] to rather obvious and rather substantial changes". The traditional notion of an orderly procession of script styles, each suddenly appearing and displacing
9243-406: The extent that the original objects represented are no longer obvious. This proto-writing system was limited to representing a relatively narrow range of ideas with a comparatively small library of symbols. This compelled innovations that allowed for symbols to directly encode spoken language. In each historical case, this was accomplished by some form of the rebus technique, where the symbol for
9360-554: The fact that the style was considered more orderly than a later form referred to as 今草 ( jīncǎo ; 'modern cursive'), which had first emerged during the Jin and was influenced by semi-cursive and regular script. This later form was exemplified by the work of figures like Wang Xizhi (303–361), who is often regarded as the most important calligrapher in Chinese history. An early form of semi-cursive script ( 行书 ; 行書 ; xíngshū ; 'running script') can be identified during
9477-616: The first official list of simplified forms was published, consisting of 324 characters collated by Peking University professor Qian Xuantong . However, fierce opposition within the KMT resulted in the list being rescinded in 1936. Work throughout the 1950s resulted in the 1956 promulgation of the Chinese Character Simplification Scheme , a draft of 515 simplified characters and 54 simplified components, whose simplifications would be present in most compound characters. Over
9594-463: The first round—but was massively unpopular and never saw consistent use. The second round of simplifications was ultimately retracted officially in 1986, well after they had largely ceased to be used due to their unpopularity and the confusion they caused. In August 2009, China began collecting public comments for a revised list of simplified characters; the resulting List of Commonly Used Standard Chinese Characters lists 8,105 characters, including
9711-465: The following decade, the Script Reform Committee deliberated on characters in the 1956 scheme, collecting public input regarding the recognizability of variants, and often approving forms in small batches. Parallel to simplification, there were also initiatives aimed at eliminating the use of characters entirely and replacing them with pinyin as an official Chinese alphabet, but this possibility
9828-460: The forms of pictographs have been simplified in order to make them easier to write. As a result, modern readers generally cannot deduce what many pictographs were originally meant to resemble; without knowing the context of their origin in picture-writing, they may be interpreted instead as pure signs. However, if a pictograph's use in compounds still reflects its original meaning, as with 日 in 晴 ('clear sky'), it can still be analysed as
9945-455: The founding of the Qin. The Han dynasty (202 BC – 220 AD) that inherited the Qin administration coincided with the perfection of clerical script through the process of libian . Eastward spread of Western learning Though most closely associated with the People's Republic, the idea of a mass simplification of character forms first gained traction in China during
10062-607: The four independent inventions of writing accepted by scholars; of these, they comprise the only writing system continuously used since its invention. Over time, the function, style, and means of writing characters have evolved greatly. Unlike letters in alphabets that reflect the sounds of speech, Chinese characters generally represent morphemes , the units of meaning in a language. Writing a language's entire vocabulary requires thousands of different characters. Characters are created according to several different principles, where aspects of both shape and pronunciation may be used to indicate
10179-649: The historical forms like seal script and clerical script. Most styles used throughout the Sinosphere originated within China, though they may display regional variation. Styles that have been created outside of China tend to remain localized in their use: these include the Japanese edomoji and Vietnamese lệnh thư scripts. Calligraphy was traditionally one of the four arts to be mastered by Chinese scholars, considered to be an artful means of expressing thoughts and teachings. Chinese calligraphy typically makes use of an ink brush to write characters. Strict regularity
10296-466: The increased usage of 朙 was followed by proliferation of a third variant: 眀 , with 目 'eye' on the left—likely derived as a contraction of 朙 . Ultimately, 明 became the character's standard form. The Book of Han (111 AD) describes an earlier attempt made by King Xuan of Zhou ( d. 782 BC ) to unify character forms across the states of ancient China , with his chief chronicler having "[written] fifteen chapters describing" what
10413-401: The initial development of Chinese writing, and has remained common throughout its subsequent history. Some loangraphs ( 假借 ; jiǎjiè ; 'borrowing') are introduced to represent words previously lacking another written form—this is often the case with abstract grammatical particles such as 之 and 其 . The process of characters being borrowed as loangraphs should not be conflated with
10530-488: The late Han, with its development stemming from a cursive form of neo-clerical script. Liu Desheng ( 劉德升 ; c. 147 – 188 CE) is traditionally recognized as the inventor of the semi-cursive style, though accreditations of this kind often indicate a given style's early masters, rather than its earliest practitioners. Later analysis has suggested popular origins for semi-cursive, as opposed to it being an invention of Liu. It can be characterized partly as
10647-459: The left, with the 月 'Moon' component on the right. Li Si ( d. 208 BC ), the Chancellor of Qin, attempted to universalize the Qin small seal script across China following the wars that had politically unified the country for the first time. Li prescribed the 朙 form of the word for 'bright', but some scribes ignored this and continued to write the character as 明 . However,
10764-452: The mainstream script underwent slow, gradual evolution during the late Shang, which continued during the Zhou dynasty ( c. 1046 – 256 BCE) until assuming the form now known as small seal script ( 小篆 ; xiǎozhuàn ) within the Zhou state of Qin . Other scripts in use during the late Zhou include the bird-worm seal script ( 鸟虫书 ; 鳥蟲書 ; niǎochóngshū ), as well as
10881-548: The method by which the meaning was originally depicted, phonographs that include a phonetic component, and loangraphs encompassing existing characters that have been borrowed to write other words. Qiu also acknowledges the existence of character classes that fall outside of these principles, such as pure signs. Most of the oldest characters are pictographs ( 象形 ; xiàngxíng ), representational pictures of physical objects. Examples include 日 ('Sun'), 月 ('Moon'), and 木 ('tree'). Over time,
10998-402: The most prominent Chinese authors of the 20th century, stated that "if Chinese characters are not destroyed, then China will die" ( 漢字不滅，中國必亡 ). During the 1930s and 1940s, discussions regarding simplification took place within the ruling Kuomintang (KMT) party. Many members of the Chinese intelligentsia maintained that simplification would increase literacy rates throughout the country. In 1935,
11115-458: The one previous, has been disproven by later scholarship and archaeological work. Instead, scripts evolved gradually, with several coexisting in a given area. Several of the Chinese classics indicate that knotted cords were used to keep records prior to the invention of writing. Works that reference the practice include chapter 80 of the Tao Te Ching and the " Xici II" commentary to
11232-405: The phonetic series of characters using 余 ( yú ; jyu4 ), a literary first-person pronoun. The Old Chinese pronunciations of these characters were similar, but the phonetic component no longer serves as a useful hint for their pronunciation due to subsequent sound shifts. The phenomenon of existing characters being adapted to write other words with similar pronunciations was necessary in
11349-428: The pictograph 大 , meaning 'large', was originally a picture of a large man, but one would need to be aware of its specific meaning in order to interpret the sequence 大鹿 as signifying 'large deer', rather than being a picture of a large man and a deer next to one another. Due to this process of abstraction, as well as to make characters easier to write, pictographs gradually became more simplified and regularized—often to
11466-489: The pictorial qualities that remained in seal script. Around the midpoint of the Eastern Han (25–220 CE), a simplified and easier form of clerical script appeared, which Qiu terms 'neo-clerical' ( 新隶体 ; 新隸體 ; xīnlìtǐ ). By the end of the Han, this had become the dominant script used by scribes, though clerical script remained in use for formal works, such as engraved stelae . Qiu describes neo-clerical as
11583-527: The primary style used for characters since. Informed by a long tradition of lexicography , states using Chinese characters have standardized their forms: broadly, simplified characters are used to write Chinese in mainland China , Singapore , and Malaysia , while traditional characters are used in Taiwan , Hong Kong , and Macau . After being introduced in order to write Literary Chinese , characters were often adapted to write local languages spoken throughout
11700-412: The promotion of small seal script by the Qin dynasty (221–206 BCE). Clerical script , which had matured by the early Han dynasty (202 BCE – 220 CE), abstracted the forms of characters—obscuring their pictographic origins in favour of making them easier to write. Following the Han, regular script emerged as the result of cursive influence on clerical script, and has been
11817-430: The public and quickly fell out of official use. It was ultimately formally rescinded in 1986. The second-round simplifications were unpopular in large part because most of the forms were completely new, in contrast to the familiar variants comprising the majority of the first round. With the rescission of the second round, work toward further character simplification largely came to an end. In 1986, authorities retracted
11934-529: The purely pictorial use of symbols disappeared, leaving only those representing spoken words, the process was complete. Chinese characters have been used in several different writing systems throughout history. The concept of a writing system includes both the written symbols themselves, called graphemes —which may include characters, numerals, or punctuation—as well as the rules by which they are used to record language. Chinese characters are logographs , which are graphemes that represent units of meaning in
12051-525: The quantities they represent. The Shuowen Jiezi is a character dictionary authored c. 100 CE by the scholar Xu Shen ( c. 58 – c. 148 CE ). In its postface, Xu analyses what he sees as all the methods by which characters are created. Later authors iterated upon Xu's analysis, developing a categorization scheme known as the 'six writings' ( 六书 ; 六書 ; liùshū ), which identifies every character with one of six categories that had previously been mentioned in
12168-465: The recently conquered parts of the empire is generally seen as being the first real attempt at script reform in Chinese history. Before the 20th century, variation in character shape on the part of scribes, which would continue with the later invention of woodblock printing , was ubiquitous. For example, prior to the Qin dynasty (221–206 BC) the character meaning 'bright' was written as either 明 or 朙 —with either 日 'Sun' or 囧 'window' on
12285-423: The regional forms used in non-Qin states. Examples of these styles were preserved as variants in the Shuowen Jiezi . Historically, Zhou forms were collectively referred to as large seal script ( 大篆 ; dàzhuàn ), a term which has fallen out of favour due to its lack of precision. Following Qin's conquest of the other Chinese states that culminated in the founding of the imperial Qin dynasty in 221 BCE,
12402-472: The result of clerical forms being written more quickly, without formal rules of technique or composition: what would be discrete strokes in clerical script frequently flow together instead. The semi-cursive style is commonly adopted in contemporary handwriting. Regular script ( 楷书 ; 楷書 ; kǎishū ), based on clerical and semi-cursive forms, is the predominant form in which characters are written and printed. Its innovations have traditionally been credited to
12519-534: The right. It developed further during the Eastern Jin (317–420) in the hands of Wang Xizhi and his son Wang Xianzhi (344–386). However, most Jin-era writers continued to use neo-clerical and semi-cursive styles in their daily writing. It was not until the Northern and Southern period (420–589) that regular script became the predominant form. The system of imperial examinations for the civil service established during
12636-426: The same character—is often non-trivial or unclear. For example, prior to the Qin dynasty the character meaning 'bright' was written as either 明 or 朙 —with either ⽇ 'SUN' or 囧 'WINDOW' on the left, and ⽉ 'MOON' on the right. As part of the Qin programme to standardize small seal script across China, the 朙 form was promoted. Some scribes ignored this, and continued to write
12753-476: The same set of simplified characters as mainland China. The first round was promulgated by the Ministry of Education in 1969, consisting of 498 simplified characters derived from 502 traditional characters. A second round of 2287 simplified characters was promulgated in 1974. The second set contained 49 differences from the mainland China system; these were removed in the final round in 1976. In 1993, Singapore adopted
12870-461: The second round completely, though they had been largely fallen out of use within a year of their initial introduction. That year, the authorities also promulgated a final version of the General List of Simplified Chinese Characters . It was identical to the 1964 list save for 6 changes—including the restoration of 3 characters that had been simplified in the first round: 叠 , 覆 , 像 ; the form 疊
12987-414: The spoken language. Some characters may only have the same initial or final sound of a syllable in common with phonetic components. A phonetic series comprises all the characters created using the same phonetic component, which may have diverged significantly in their pronunciations over time. For example, 茶 ( chá ; caa4 ; 'tea') and 途 ( tú ; tou4 ; 'route') are part of
13104-488: The traditional and simplified Chinese orthographies. The Chinese government has never officially announced the completion of the simplification process after the bulk of characters were introduced by the 1960s. In the wake of the Cultural Revolution , a second round of simplified characters was promulgated in 1977—largely composed of entirely new variants intended to artificially lower the stroke count, in contrast to
13221-817: The traditional character 強 , with 11 strokes is standardised as 强 , with 12 strokes, which is a variant character. Such characters do not constitute simplified characters. The new standardized character forms shown in the Characters for Publishing and revised through the Common Modern Characters list tend to adopt vulgar variant character forms. Since the new forms take vulgar variants, many characters now appear slightly simpler compared to old forms, and as such are often mistaken as structurally simplified characters. Some examples follow: The traditional component 釆 becomes 米 : The traditional component 囚 becomes 日 : The traditional "Break" stroke becomes
13338-516: The use of characters entirely. Instead, Chao proposed that the language be written with an alphabet, which he saw as more logical and efficient. The alphabetization and simplification campaigns would exist alongside one another among the Republican intelligentsia for the next several decades. Recent commentators have echoed some contemporary claims that Chinese characters were blamed for the economic problems in China during that time. Lu Xun , one of
13455-579: The wars of unification. The popularity of this form grew as writing became more widespread. By the Warring States period ( c. 475 – 221 BCE), an immature form of clerical script ( 隶书 ; 隸書 ; lìshū ) had emerged based on the vulgar form developed within Qin, often called "early clerical" or "proto-clerical". The proto-clerical script evolved gradually; by the Han dynasty (202 BCE – 220 CE), it had arrived at
13572-461: Was abandoned, confirmed by a speech given by Zhou Enlai in 1958. In 1965, the PRC published the List of Commonly Used Characters for Printing [ zh ] (hereafter Characters for Printing ), which included standard printed forms for 6196 characters, including all of the forms from the 1956 scheme. A second round of simplified characters was promulgated in 1977, but was poorly received by
13689-498: Was officially closed down on 18 September 2018 with the arrival of C151C trainsets. Nishimatsu-Lum Chang Joint Venture had won the contract 101 on 8 September 1984. On 4 July 1985, there was a MRT mishap where four workers were trapped within 15 minutes. The MRT had built rail tracks for testing trains in 1986 -1987. On 11 February 2007, SMRT Organised the SMRT Cram Jam! cum Learning Journey and Charity Bazaar to raise funds for
