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 name
Because the small number of Chinese surnames leads to confusion in social environments, and because some Chinese parents have a desire to give individuality, some Chinese have received unusual given names. As of April 2009, about 60 million Chinese people have unusual characters in their names. A 2006 report by the Chinese public security bureau stated that of about 55,000 Chinese characters used in the People's Republic of China, only 32,232 of those are supported by the ministry's computers. The PRC government has asked individuals with unusual names to change them so they can get new computer-readable public identity cards, and the diversity prevents them from receiving new identity cards if they do not change their names.
