CJK characters
Chinese is written almost exclusively in Chinese characters. It requires over 3,000 characters for general literacy, but up to 40,000 characters for reasonably complete coverage. Japanese uses fewer characters — general literacy in Japanese can be expected with 1,945 characters. The use of Chinese characters in Korea is becoming increasingly rare, although idiosyncratic use of Chinese characters in proper names requires knowledge (and therefore availability) of many more characters. However, even today, students in South Korea are taught 1,800 characters.
Zhongwen Da Cidian
This encyclopedic dictionary includes 49,905 Chinese characters arranged under the traditional 214 Kangxi radicals. Each character entry shows the evolution of graphic forms (such as small seal script), gives pronunciations, and chronological meanings with sources. Words, phrases, and four-character idioms are given under the head character entry, arranged according to the number of strokes in their components. "There are many phrases under some characters," note Teng and Biggerstaff (1971:133), for example, 3,417 under "yi" (一 "one") and 1,398 under "huang" (黄 "yellow").
