The 1615 Zìhuì is a Chinese dictionary edited by the Ming Dynasty scholar Mei Yingzuo (梅膺祚). It is renowned for introducing two lexicographical innovations that continue to be used in the present day: the 214-radical system for indexing Chinese characters, which replaced the classic Shuowen Jiezi dictionary's 540-radical system, and the radical-and-stroke sorting method.
