Zhōu Xīngsì 周興嗣 (d. 521), zì Sīzuǎn 思纂, was a Liáng-dynasty literary official best known as the compiler of the Qiānzì wén 千字文 (“Thousand-Character Classic”), a primer of one thousand non-repeating characters arranged in rhymed quatrains, composed at the command of Emperor Wǔ (Liáng Wǔdì) using characters drawn from the calligraphy of Wáng Xīzhī 王羲之. The Qiānzì wén became the standard literacy primer of East Asia and the model for countless subsequent thousand-character pedagogical anthologies, including the Kamakura medical primer Yījiā qiānzì wén by 惟宗時俊 Korēmune no Tokitoshi (KR3ea033).
