As Chinese ancient poetry had developed to the Northern and Southern Dynasties (NSD), it was no longer as various and changeable as that in the era of the Classic of Poetry (Shijing), but it still had its own poetic style in NSD. When the writer sorted the rhymes in the poetry of the NSD, he found that rhymes in the poetry of the NSD possessed the characteristics which weren't presented in Shijing though they appeared to have relatively less similarities with Shijin on using rhymes. Besides, some of the rhyme schemes in the NSD are not only equipped with the characteristics of versification, they can also help us categorize the boundary of rhyme groups at that time. For instance, "rhyming in the first sentence" when changing rhymes is apparently a unique characteristic of the poetry in NSD. On the other hand, if we use the 206 rhymes in Guangyun as criteria, the poetic characteristics in NSD could also assist us to classify the same and different rhymes. Therefore, with observation and analysis, this research focused on "rhyming in the first sentence" when changing rhymes. Based on the rhyming places, the rhymes in the poetry of NSD could be divided into two categories respectively: "rhyming in first sentence with its own rhyme" and "rhyming in the first sentence with a former rhyme".
