As there is a direct connection between Daoism and Laozi, some suggest he played a major role in the creation of Chinese alchemy. Zhou Dynasty philosopher Zou Yan is said to have written many of the alchemical books, although none of them have ever been found, nor have the existing ones been credited to him. The likeliest proponents of Chinese alchemy are as previously stated, Laozi, and Zhang Daoling as well as Zhuangzi. Each of these men are major icons in Daoist teachings. Although these three are credited with the creation of alchemy, there is no definitive proof to suggest or dispute that they were responsible for its creation.
