Abstract: XH-XD Culture is the leading culture in the Chinese tradition. The step from XH-XD Culture to Yhxdology is not only an improvement but a discipline construction. This discipline construction is completely in conformity with the demands of the time to make Chinese excellent traditional culture going "creative transformation and development" suggested by CPC, and with "cultural confidence" provoked by Secretary General Xi Jinping in the report of 19th CPC National Congress. All of these can be beneficial for us to realize cultural self-consciousness and cultural confidence on the basis of self-knowledge of Chinese traditional culture. Yhxdology is also helpful to overcome the structural dilemma, so as to achieve the combination of scientific researches and teaching to integrate different achievements inherently.
