On Heritage of Philosophical Thought of CHENG Yi

There was a development of the heritage concerning the process from LUO Culture of the two CHENGs( CHENG Yi and CHENG Hao) to the MIN Culture of ZHU Xi and from the philosophical thought of the two CHENGs to that of ZHU Xi. Among the CHENG Family' s disciples, the Fujianese YANG Shi and LUO Cong-yan were the pioneers of the MIN Culture as well as the successors of LUO Culture and philosophical thought of the two CHENGs. They totally inherited the philosophical thought of the two CHENGs without significant development. LI Tong not only carried on but also pushed forward the masters' philosophy. LI Tong deepened the theory of Taiji in the way of applying the combination of the philosophy of CHENG Yi and the theory of Taiji of ZHOU Dun-yi. ZHU Xi epitomized the theory of MIN Culture and he was also the disseminater of the two CHENGs' LUO Culture. He systematized the theory of spirit and matter by CHENG Yi and perfected the doctrine that the spirit came before the matter and developed the theory of acquiring knowledge by the way of studying the principles of matter and formed a set of integrated theoretical system of CHENG-ZHU' s philosophical thought.
