New Research On DengYunMenFa Of Song Yuan Dynasty

At present there exist five rhyme diagrams of Song Yuan Dynasty, they are YunJing, QiYinLue, SiShengDengZi, QieYunZhiZhangTu and JingShiZhengYinQieYunZhiNan. MenFaYuYaoShi attached to JingShiZhengYinQieYunZhiNan epitomizes various MenFa rules, and we also can see some MenFa rules in SiShengDengZi and QieYunZhiZhangTu. All of them are very important materials for us to study DengYunMenFa of Song Yuan Dynasty.MenFa are used to explain the contradiction between rhyme works and rhyme diagrams, and the contradiction between fanqie in rhyme diagrams and actual sounds. From the MenFa, we can find out the phonetic system and the tendency of phonetic development. After careful analysis, we find that LeiGe reflects the separation of sheshang sounds from tongue sounds. QingZhongJiaoHu reflects the separation of light bilabial sounds from heavy bilabial sounds. ZhenJiu and KeQie reflect the collocation of Jingxi. ZhengYinPingQie and JiYunPingQie reflect the dividing of deng in Zhaoxi. From YuXiaPingQie we can find the obvious boundary between Yusan and Yusi. RiJiPingQie reflects the special collocation of Rimu with the Third Deng rhyme, TongGuang and CuXia reflect the matter of ChongNiu. NeiWai reflects the influence of NeiZhuan and WaiZhuan on fanqie.In addition, after comparing those MenFa of different rhyme diagrams, we can see that MenFa were keeping developing continuously and the development were following some rules. On the one hand, JingZhaoHuYong, YuXiaPingQie and RiJiPingQie just exist in MenFaYuYaoShi, and these MenFa were not being at the beginning, but appeared during late time, which reflects that MenFa were changing from simple to complex. On the other hand, the changes of MenFa also reflect some phonetic phenomena and different statements about LeiGe means that the separation of sheshang sounds from tongue sounds and the separation of light bilabial sounds from heavy bilabial sounds didn't occur at the same time.
