The Zìhuì (Chinese: 字彙/字汇; Wade–Giles: Tzu Hui; literally: "lexicon") is a Chinese dictionary, edited by Mei Yingzuo (梅膺祚) during the late Ming Dynasty and published in 1615, the forty-third year of the Ming Wanli Emperor. The work is divided into 14 scrolls (juan 巻) and contains a total of 33,179 Chinese characters. It was the first dictionary to introduce the modern radical-stroke system. Whilst the ancillary first and last fascicles explain topics like stroke order and radicals, the main ones are named after the twelve Earthly Branches. The Qing Dynasty scholar Wu Renchen (c. 1628 – c. 1689) published the 1666 Zihui Bu (字彙補 "Zihui supplement").
