홍무정운역훈의 운류와 홍무정운의 반절하자

This is a study of a comparison of the fanqie in the Hongwuzhengyun(1375) and the rhymes of the Hongmujeongunyeokhun(1455). As a result of the whole comparison, it is confirmed that the rhymes of the Yeokhun didn`t follow the fanqie in the Zhengyun in spite of many similarities between the two systems.
