Although there are more than 40,000 Chinese characters in written Chinese, many are rarely used. Studies have shown that full literacy in the Chinese language requires a knowledge of only between three and four thousand characters.

In Chinese, the Thousand Character Classic is a 1000-character poem in which each character is used exactly once; however, it does not include all Chinese characters. The single character (permanence) incorporates every basic stroke used to write Chinese characters exactly once, as described in the Eight Principles of Yong.
