During the Qin dynasty (221–207 bc) the first government standardization of the characters took place, carried out by the statesman Li Si. A new, somewhat formalized style known as seals was introduced—a form that generally has survived until now, with only such minor modifications as were necessitated by the introduction of the writing brush about the beginning of the 1st century ad and printing about ad 600. As times progressed, other styles of writing appeared, such as the regular handwritten form kai (as opposed to the formal or scribe style li), the running hand xing, and the cursive hand cao, all of which in their various degrees of blurredness are explicable only in terms of the seal characters.

The Qin dynasty standardization comprised more than 3,000 characters. In addition to archaeological finds, the most important source for the early history of Chinese characters is the huge dictionary Shuowen jiezi, compiled by Xu Shen about ad 100. This work contains 9,353 characters, a number that certainly exceeds that which it was or ever became necessary to know offhand. Still, a great proliferation of characters took place at special times and for special purposes. The Guangyun dictionary of 1008 had 26,194 characters (representing 3,877 different syllables in pronunciation). The Kangxi zidian, a dictionary of 1716, contains 40,545 characters, of which, however, fewer than one-fourth were in actual use at the time. The number of absolutely necessary characters has probably never been much more than 4,000–5,000 and is today estimated at fewer than that.

The 20th century

By the 20th century the feeling had become very strong that the script was too cumbersome and an impediment to progress. The desire to obtain a new writing system necessarily worked hand in hand with the growing wish to develop a written language that in grammar and vocabulary approached modern spoken Chinese. If a phonetic writing system were to be introduced, the classical language could not be used at all because it deviates so markedly from the modern language. None of the earlier attempts gained any following, but in 1919 a system of phonetic letters (inspired by the Japanese syllabaries called kana) was devised for writing Mandarin. (In 1937 it received formal backing from the government, but World War II stopped further progress.) In 1929 a National Romanization, worked out by the author and language scholar Lin Yutang, the linguist Zhao Yuanren, and others, was adopted. This attempt also was halted by war and revolution. A rival Communist effort known as Latinxua, or Latinization of 1930, fared no better. An attempt to simplify the language by reducing the number of characters to about 1,000 failed because it did not solve the problems of creating a corresponding “basic Chinese” that could profitably be written by the reduced number of symbols.

The government of China has taken several important steps toward solving the problems of the Chinese writing system. The first and basic step of making one language, Modern Standard Chinese, known throughout the country has been described above. In 1956 a simplification of the characters was introduced that made them easier to learn and faster to write. Most of the abridged characters were well-known unofficial variants, used in handwriting but previously not in printing; some were innovations. In 1958 the previously mentioned romanization known as pinyin zimu was introduced. This system is widely taught in the schools and is used for many transcription purposes and for teaching Modern Standard Chinese to non-Han Chinese peoples in China and to foreigners. Pinyin romanization, however, is not intended to replace the Chinese characters but to help teach pronunciation and popularize the Beijing-dialect-based Putonghua.
