The Zhengzitong was a 17th-century Chinese dictionary. The Ming dynasty scholar Zhang Zilie originally published it in 1627 as a supplement to the 1615 Zihui dictionary of Chinese characters, and called it the Zihui bian. The Qing dynasty author Liao Wenying bought Zhang's manuscript, renamed it Zhengzitong, and published it under his own name in 1671.
