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.
Chinese Character Simplification Scheme
The "Chinese Character Simplification Scheme" is divided into three parts. The first part consists of 230 simplified characters; the second part consists of 285 simplified characters; the third part consists of 54 simplified radicals. The first and second parts differ in their time of implementation; the first part was to be implemented the day after the announcement, while the second part was mostly implemented in three batches later between 1956 and 1959 after further trials and slight changes, leaving out 28 simplified characters which were implemented in 1964 when the "List of Simplified Chinese Characters" was published.
