In the warring states period, the school of Mozi's philosophy was considered very influential. However, as time went by to the early Han dynasty, Moism was on the down grade. As one of the four main philosophic schools, Moism lost its dominant status in the world. What's worse, the famous historian of West Han dynasty Sima Qian even made little mention about the founder Mozi, making the life experiences of Mozi more difficult to be investigated. In the time of Eastern Jin dynasty, Ge Hong, who made pills of immortality, proposed the deification of Mozi, making the founder immortal. In response to Ge Hong's deification, many works of Taosim borrowed the thoughts of Mozi. In fact, Moism belonged to a philosophic school; on the contrary, Taoism was classified as a religious belief. These two should be completely different to each other. However, this paper tries to focus on the three chapters ”Tian Zhi”, ”Ming Gui”, and ”Wu Xiang Wu Chang Sheng” in Mozi to argue that there should be some relevance between the religious belief Taoism and Moism. Moreover, in this paper, the author tried to define clearly why the image of Mozi would have become so inconsistent in different periods.
