Chinese as a second language acquisition research has become a new area of research on teaching Chinese as a foreign language. The new field has been started from now through more than twenty years. Chinese second language teaching model research can be effective in studying Chinese theoretical research and teaching practice combined, and can improve the efficiency of Chinese second language teaching. After careful carding, we think that existing research home and abroad about Chinese as a second language teaching model has made significant progress, but basically it is still in the stage of exploration. There is a lot of space for further study.
