Abstract: New changes appeared in the development of Confucianism in the Northern Song Dynasty. Neo Confucianists explored Confucian classics and found the true Confucian way, which they called "Taoism" at that time. In the middle of the Southern Song Dynasty, Taoism was divided into two schools: one is Neo Confucianism represented by Zhu Xi, and the other is philosophy of mind represented by Lu Jiuyuan. The two had differences in the ways of "moral compliance" and "inquiry learning by Tao", resulting in dispute of "similarities and differences between Zhu and Lu". In the middle of Ming Dynasty, Wang Yangming gave play to the theory of philosophy of mind and founded the theory of "ideal personality", and the dispute between Neo Confucianism and philosophy of mind occurred again in the academic circle. In order to calm and reconcile the debate, Wang Yangming pointed out that Zhu Xi repented of his scholarly methods of preaching, annotation and interpretation in his later years, which was consistent with the purpose of psychology of mind and the theory of "ideal personality", so he compiled The Conclusion of Zhu Xi's Later Years. Although this theory has been criticized in academic circles, it contributes to the prevalence of Yangming studies. However, Zhu Xi and his friends occasionally expressed the lack of study to "moral compliance" in their letters, of course this was an accidental self modesty. A few years before his death, he was still committed to the interpretation and textual research of Confucian classics and other classics without repentance. The Conclusion of Zhu Zi's Later Years can not hold water in fact, neither can be established as an academic theory, even though it is the desire to reconcile or connect "Zhu Lu" and "Zhu Wang" subjectively and reluctantly.
