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".
Thousand Character Classic
The Thousand Character Classic (), also known as the Thousand Character Text, is a Chinese poem that has been used as a primer for teaching Chinese characters to children from the sixth century onward. It contains exactly one thousand characters, each used only once, arranged into 250 lines of four characters apiece and grouped into four line rhyming stanzas to make it easy to memorize. It is sung in a way similar to children learning the Latin alphabet sing an "alphabet song." Along with the "Three Character Classic" and the "Hundred Family Surnames", it formed the basis of literacy training in traditional China.
