Abstract: For a long time, people have accepted the propaganda effect of the word “Neo-Confucianism of Song and Ming Dynasties”, and what is the status and function of geography at the time of Song Dynasties? There are many misunderstandings. Neo-Confucianism is only a school of Song School, which appeared later. Although in the Yuanyou period, the prosperity was temporary, but the prosperity was not long, that is to say, it was blocked. The main reasons are: cliques attack each other and dispute endlessly; empty talk makes no difference to reality; the need of the current situation, and paying attention to merit. For many reasons, the development of Neo-Confucianism has been blocked, restricted, alienated and transformed for a long time, and there are many tendencies like: the morality is sanctimonious, and the hypocrisy is mixed. White-headed scholars clean up and retire. There are people who have timely transformed and advocated merits. There are great masters of Collective Neo-Confucianism who adhere to Yiluos orthodoxy.

Key words: Song Xue, Neo-Confucianism, Taoism, pseudo-science, achievement
