Character amnesia
It is difficult to establish exactly how many different Chinese characters are in use today; the new HSK, a widely used proficiency test for Standard Chinese as a second language, tests over 2,600 different characters, whilst in 1988 the People's Republic of China published the "List of Commonly Used Characters in Modern Chinese" which contains 7,000 different characters. In Japan, where a smaller set of characters are in general usage, the Japanese Ministry of Education prescribes the teaching of 2,136 kanji in primary and secondary school in a list called the jōyō kanji, meaning "regular-use Chinese 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.
