This paper aims to study the phonological system of 《Zhongyuan yayin》, and that of relations between 《Zhongyuan yinyun》and 《Zhongzhou yinyun》and basic dialect of 《Zhongyuan yayin》. The formal aspect of these three rhyme books and phonological system are all different, so we can see that the basic dialect of these books are all different. The previous studies insist that the basic dialect of 《Zhongyuan yayin》is Jingxing dialect, but the sound type of palatal nasal in 《Zhongyuan yayin》is also found in other Jilu dialect regions. Besides, the type of changes in entering tone is different in Jinxing dialect. So, we can see the basic dialect of《Zhongyuan yinyun》is unrelated with Jingxing dialect. The sound of palatal nasal and rhyme of Dangjiang(宕江) group in Beijing dialect is same with Beijing dialect, there is possibility that 《Zhongyuan yayin》is based on Beijing dialect.
