Combined with the academic researches of Mao Zedongs mother tongue，this paper objectively analyzes the dialect rhymes in Mao Zedongs Poems, which embodies the dialect phonetic phenomenon of Maos writings. The dialect rhyme of Mao Zedongs poems can be divided into two kinds. Firstly, it is the unconscious use of dialect rhyme specifically in his metrical poetry. Second, it is the conscious use of dialect rhyme specifically in his Ci. On the one hand, Mao Zedong, when making use of dialect in his poems, has its specifically social and historical reasons; on the other hand, he makes conscious use of dialect, in order to better pursue the emotion expression. Maos practices of rhyming according to dialect have reflected the correct direction of traditional poems that writing should be a modern spoken voice system to rhyme.
