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 alphabet
There are and have been several Chinese alphabets, that is pre-existing alphabets adapted to write down the Chinese language. However, the standard Chinese writing system uses a non-alphabetic script with an alphabet for supplementary use. There is no original alphabet native to China. China has its Pinyin system though sometimes the term is used anyway to refer to logographic Chinese characters ("sinograms"). It is more appropriately used, though, for phonemic transcriptions such as pinyin.
