Wang Tingxiang was an important philosopher in the Ming Dynasty. He took Yuan-qi as substance to establish his philosophic system, and criticized the dominant views of the Song Dynasty. His criticisms of Li-Sheng-Qi-Shuo and Xing-Shan-Lun are the focus of his philosophic discussion, therefore we can grasp his philosophic core through the discussion of these two questions. Furthermore, because his critical object is Zhuzi, referring to Zhuzi's philosophy can show the difference between them. After the discussion, we will find that his philosophy is quite consistent, so he can form his theory. But his critical object also has his own philosophy. In other words, for the same questions, both Zhuzi and Wang Tingxiang can present respective and reasonable interpretations. Their differences are different philosophies, but we can't take one's as the standard to belittle another.
