Wucaishen is a kind of Caishen in Chinese folk belief. There is a distinction between the God of wealth and the God of wealth. The God of wealth is Bigan, Fan Li and Li Guizu, and the God of wealth is Guan Yu, Chai Rong and Zhao Gongming.
The emperors of all dynasties regarded Guan Yu as the embodiment of loyalty, holding the green dragon Yan Yue Dao, with a powerful image and a sense of righteousness.
In the third year of Yongzheng (1725) in the Qing Dynasty, the imperial court issued a decree that the Guandi temple was used as the temple of martial arts and was incorporated into the sacrificial ceremony. All the officials of culture and martial arts and the people of all provinces and counties carried out two sacrificial ceremonies in the spring and Autumn period according to the sacrificial ceremony of the imperial prison for Confucius. Since then, Guan Yu has become the main god of national sacrifice, and has reached the position of keeping abreast with Confucius.
