本文指出：由于最初确定汉藏语系依据的类型学的相似不能作亲属关系的依据，汉语及南方民族语少量形态也不可靠，后期寻找同源词证明侗台语归属分歧大，故在此基础上，近二十年学术界在理论方法有新突破：徐通锵的三步法，邢公畹的深层对应法，尤其是陈保亚无界有阶理论及核心词分阶考察法使汉语与南方民族语言关系研究更进了一步。 This paper points out that due to the fact that the similarity of typology based on the Sino-Tibetan language was initially determined, the minor forms of Chinese and southern national languages ​​are not reliable. Based on the past two decades, academic circles have made new breakthroughs in theoretical methods: Xu Tongqiang’s three-step method, Xing Gongxun’s deep correspondence law, especially Chen Baoya’s unbounded and even-order theory and the core word hierarchical approach make the relationship between Chinese and the southern ethnic languages Take one step further.
