Taoism is a school of philosophy originating from Lao Zi and Zhuang Zi thoughts. Originating in the Spring and Autumn Period, Taoist philosophy of cosmos rose through the Han, Wei and Jin Dynasties, and made great achievements in Sui, Tang and Five Dynasties, and then different factions converged in the Ming and Qing Dynasties. Taoism's view of cosmogenesis has developed successively from Lao Zi's Tao(道) theory to Zhuang Zi's Qihua（气化）theory and Wen Zi's Hunyi（浑一）and Taiyi（太一）theories, then to Wang Bi's Non-being（无） theory and Cheng Xuanying's Qi（气）theory, all of which ended up in the integration of three religions ever since Song and Ming Dynasties.
