Zihui

The Zihui () was a 1615 Chinese dictionary, edited by Mei Yingzuo (梅膺祚) during the late Ming Dynasty. It was the first dictionary to introduce the modern radical-stroke system. The Zihui has 14 fascicles (juan 巻 "scrolls") with 33,179 character entries. While 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 (吳任臣, 1628-1689) published the 1666 Zihui bu (字彙補 "Zihui supplement").
