What is not in Yin and Yang in China mythology is the Heavenly Palace?

In China's mythology, it is the Heavenly Palace where Yin and Yang are absent.

According to historical data, it is the Heavenly Palace that is not in the shadow in China mythology. Tiangong, also known as Wei Zi Palace, is the palace where the Emperor of Heaven lived in China myths and legends.

China myth is the product of ancient traditional culture in China, which reflects the simple thoughts of children in early China and the primitive fantasies of ancient people about natural phenomena and social life. The stories and legends expressed through supernatural images and fantasy forms are the natural and social forms themselves processed by people's fantasies in an unconscious artistic way.
