What does the legend of the Five Ghosts refer to?

The Five Ghosts, also known as Five Disasters, Five Disasters Ambassadors and Five Disasters Envoys, are the gods of plague in Han folklore. They are Zhang in spring, Liu Yuanda in summer, Zhong and General Manager in autumn and winter. They are the plague gods believed by the Han people. Every year, some temples worship five ghosts for the safety of livestock, which means five ghosts. It has pinned the good wishes of the working people of the Han nationality to exorcise evil spirits, avoid disasters and pray for blessings.

According to the "Three Religions Origin Searching for God", in June of the 11th year of Emperor Wendi (596), there were five strong men in the air, three or five feet from the ground, wearing five-color robes, each holding one thing. One person holds a structure and a jar, another person holds a purse and a sword, another person holds a fan, another person holds a hammer, and another person holds a brazier. The emperor asked Tai Shizhang why this is a god and what is the blessing of the Lord? Answer: this is the five parties Luxe, five ghosts in the sky and five disasters on the ground. Zhang in spring, Liu Yuanda in summer, Zhong in autumn and Zhong in winter are responsible for history and literature. There are unexpected events in the sky, and there is no escape. When there was a plague on fruits, many China people died of illness.

Emperor Wendi of Sui Dynasty set up a shrine to worship. On June 27th, he went down to the swamp and appointed Wu Fang Lux as general. Shi, the general manager of Lux in yellow robe, Zhang in green robe, Liu Yuanda in red robe, Li Tu in red robe, Qiu Wen in white robe and Winter Wen in Chinese and black robe, were named generals, and May 5 was designated as the sacrifice day. The Tang Dynasty attacked the Sui Dynasty to commemorate the Five Disaster Messengers.

According to legend, Kuang Fu's real people once took the thunder as the department, and it is also said that Emperor Wenchang once surrendered the thunder to the French platform, specializing in the duties of "collecting plague, taking poison and sweeping filth" to bless people and animals to prosper and harvest crops. After Taoism, it evolved into the plague in teaching, so Wenchang was honored as the ancestor of the plague, and Wu Wen was also honored as the plague. In the forty-fourth year of Qianlong (1779), Qiqu Mountain Temple began to worship Wen's ancestors and held autumn festivals, so the autumn temple fair rose in August.
