There is no sleeping god in China's myth system, but there are many allusions and characters related to sleeping.
If you have to find a sleeping god, I believe it is appropriate to ration the Duke of Zhou.
Duke Zhou, surnamed Ji Mingdan (Ji Dan), is the fourth son of King Ji Chang of Zhou Wen and the younger brother of Zhou Wuwang. He helped Zhou Wuwang invade Zhou Wang in the East twice and made music. Because he is Duke of Zhou, he is called Duke of Zhou.
Duke Zhou was an outstanding politician, strategist, thinker and educator in the early years of the Western Zhou Dynasty. He was honored as a "Yuan Saint" and was the pioneer and founder of Confucianism.
Seven years after the Duke of Zhou's regency, he put forward various fundamental laws and perfected the patriarchal clan system, enfeoffment system, eldest son inheritance law and Jing Tian system. In the seventh year, the Duke of Zhou became king and formally established the eldest son inheritance system in the Zhou Dynasty. The biggest feature of these systems is the combination of family and state, politics and ethics. The formation of this system had a great influence on the feudal society in China, which laid the foundation for Zhou's 800-year rule. Jia Yi commented on Duke Zhou as follows: Before Confucius and after the Yellow Emperor, Duke Zhou was the only person with close ties in China.
Duke Zhou is our ancient cultural heritage and the crystallization of the wisdom of working people. Although it is difficult to be elegant, it is widely circulated among the people. Later generations wrote it in the name of Duke Ji Dan of Zhou. Everyone must dream. Dreams and people are the same as souls and people. They come with them, go with them and accompany people all their lives. As long as the thinking ability of the human brain is still there, dreams will always exist. Dreams have no hierarchy, no age, no hierarchy, no gender, no Chinese or foreign, but the contents of dreams are different.
