There are scholars who have already done some research on the sound strata of Yu鱼rhyme in Southern Wu dialects such as Mei Zulin (2001) and Chen Zhongmin (2013). Accordingly, this article presents a further research, which has found eight sound strata of Yu鱼 rhyme in Southern Wu dialects. Layer I merges into the Yu鱼 and Ma麻 rhymes. Layer II is that Yu鱼 rhyme stands alone. Layer III merges into the Yu鱼 and Hou侯 rhymes. Layer IV and V are both Yu鱼 and Zhi支 rhymes, sharing the same pronunciation. Layer V is the result of some dropping midials from Layer VII. Layer VI includes the Yu鱼 Zhi支 Zhi脂 Zhi之 and Wei微rhymes. Layer VI with high vowels becomes layer VII. Layer VIII consists of Yu鱼 and Yu虞 rhymes. The layer I originated in Western Han Dynasty, layer II, III, IV, V, VI and VII are all as a consequence of Yu鱼 rhyme changed in Six Dynasty (Wei Jin Nan Bei Chao), the layer VIII is from late Tang period to five dynasties and ten kingdoms (Wu Dai Shi Guo) period. The article also discusses the ways to distinguish between the cognate stratum and the heterogeneous stratum. Layer I, II, III, IV, V, VI and VII are all cognate strata from lexical diffusion of the evolution in Southern Wu dialects while layer VIII is a heterogeneous stratum. Meanwhile, this article has reconstructed the process of changing cognate strata.
