Respected as the first ancestor of Chinese nation, Yellow Emperor has always been worshipping as the ancestor god in Taoism God System. What's more, with his dual identities as both heroic and humane ancestors, he is deemed as an immortal god as well as the very first Taoist god. Exploring how Taoism worships Yellow Emperor, which shapes his deification while presenting the analysis and observation of the myths of Yellow emperor, which are recorded in Taoism God narrations, this paper points out that all the sects in Taoism are dedicated to the construction of Yellow Emperor belief which has been formed by the compilations in Yellow Emperor's name in Daozang as well as the worship of Yellow Emperor in various religious practices in Taoism.

Meanwhile, the connotations and features of God belief in Taoism are reflected.
