extension-Taoism

Taoism is a native religion in China, with "Tao" as its highest belief. Fang Xianjia, which originated in ancient China during the Spring and Autumn Period and the Warring States Period, is an original religious form of polytheism that worships many gods. Its main purpose is to pursue immortality, attain enlightenment and become immortal, and help the world and save people. It occupies an important position in the traditional culture of ancient China and develops actively in the modern world. Although Taoism has been one of hundred schools of thought since the Warring States Period, Taoism deified the former moral philosopher. It was not until the late Han Dynasty that the cult came into being, and the Tianshi in Yizhou (present-day Sichuan) honored Laozi as a grand old gentleman. By the Southern and Northern Dynasties, the religious form of Taoism was gradually improved. In the Tang Dynasty, Lao Zi was honored to beautify the Tang royal family, saying that Lao Zi was the ancestor of the Tang family.
