There is no accurate figure for the number of Chinese characters, but it is about nearly 100,000 (the Chinese character library of Beijing Guoan Consulting Equipment Company has 91,251 Chinese characters), and there are only a few thousand Chinese characters in daily use. According to statistics, 1,000 commonly used words can cover about 92% of written materials, 2,000 words can cover more than 98%, and 3,000 words have reached 99%. The statistical results of simplified and traditional Chinese are not much different.
The total number of Chinese characters that have appeared in history is more than 80,000 (some say there are more than 60,000), most of which are variant characters and rare characters. The vast majority of variant characters and rare characters have died out naturally or been standardized. Except for ancient Chinese characters, they generally only appear occasionally in names of people and places. In addition, following the first batch of simplified characters, there are also a batch of "two simplified characters" that have been abolished, but there are still a few characters that are popular in society.
The first statistics on the number of Chinese characters was conducted by Xu Shen of the Han Dynasty in "Shuowen Jiezi", which included 9353 characters. Later, the "Yupian" written by King Gu Ye of the Southern Dynasties was recorded to contain 16,917 words, and the "Daguangyihui Yupian" revised on this basis was said to have 22,726 words. After that, Lei Pian, compiled by officials in the Song Dynasty, contained more characters, with 31,319 characters; Ji Yun, another book compiled by officials in the Song Dynasty, contained 53,525 characters, which was once the book with the most characters.
In addition, some dictionaries also include more characters, such as the Qing Dynasty's "Kangxi Dictionary" with 47,035 characters; Japan's "Dahanwa Dictionary" with 48,902 characters and 1,062 appendixes; Taiwan's "Chinese Dictionary" "Big Dictionary" contains 49,905 characters; "Big Chinese Dictionary" contains 54,678 characters. The book with the largest number of published words in the 20th century was "Chinese Character Ocean", containing 85,000 words.
Among the Chinese character computer coding standards, the current largest Chinese character coding is Taiwan’s “National Standard” CNS11643. Currently (4.0) *** includes 76,067 verifiable traditional, simplified, Japanese, and Korean Chinese characters. However, it is not popular and is only used in a few environments such as household registration systems. The Big Five code commonly used by Taiwan and Hong Kong contains 13,053 traditional Chinese characters. GB18030 is the latest internal code character set of the People's Republic of China. GBK contains 20,912 simplified, traditional, Japanese, and Korean Chinese characters, while the early GB2312 contains 6,763 simplified Chinese characters. Unicode's basic Chinese, Japanese and Korean unified ideographic character set contains 20,902 Chinese characters, and there are two extension areas, with a total of more than 70,000 characters.
The initial Chinese character system did not have enough characters, and many things were represented by Tongjia characters, which caused great ambiguity in the expression of the characters. In order to improve the clarity of expression, Chinese characters have gone through a stage of gradual complexity and a large increase in the number of characters. The excessive increase in the number of Chinese characters has caused difficulties in learning Chinese characters. The meaning that a single Chinese character can represent is limited, so many single Chinese meanings are represented by Chinese words, such as common two-character words. The current development of Chinese writing is mostly directed towards the creation of new words rather than new characters.
