"Dui Yun Yin Xun"is one of the eight kinds of"Ming Tou Hao Yang"in Si Sheng Pian Hai,but has always been mistaken as the source document of the collection of characters in Si Sheng Pian Hai.In fact,it is an accompanying text annotation made by Han Daozhao to modify the phonetic instruction of some characters from Yu Pian,rather than a book of characters.The words"Ming Tou Hao Yang"only govern the next word.This is a mistake in Han Daozhao's dictionary compilation.The rhyme in"Dui Yun Yin Xun"refers to Wu Yin Ji Yun in the Taihe period during the reign of Emperor Zhangzong of the Jin Dynasty.
