Abstract: The ideas of "six schools" and "nine streams" are the academic genealogy of the scholars in the Han Dynasty, and they are still the basic frame of reference for the scholars in the pre-Qin period. Since modern times, the academic circle has constantly questioned this framework from the perspectives of concepts, methods and new materials. Many scholars, on the conceptual level, interpreted the Jia (literally meaning family) discussed by scholars in the pre-Qin, Qin and Han dynasties as the "school" in the modern sense, but in fact it is difficult to fully correspond to the historical meaning of "family". Yiwenzhi in the History of Han Dynasty is regarded as a narrow category of bibliography, which underestimates its academic value. The discovery of a large number of new materials filled in the "blank" of some academic history of pre-Qin period, but there was a tendency of overestimating the academic history value of unearthed documents. However, the introduction of the new method provided a new perspective for the study of the scholars in the pre-Qin period, but it took the research framework of scholars in the Han dynasty as the opposite and ignored its methodological value of "equality". To be fair, under the current conditions, the discovery of new materials, the introduction of new concepts, and the introduction of new methods were not enough to shake the research framework of scholars in the Han dynasty. On the contrary, on a deeper level, it was once again proved that the research results of scholars in the Han dynasty on the genealogy of thoughts of various scholars in the pre-Qin period were still basic and instructive.
