In the history of China, Emperor Gaozu, Wei Wendi and Song Wudi caused hallucinations. As far as Emperor Gaozu Liu Bang is concerned, it is said that one day his mother was lying on the dam of a pond to rest. As a result, it didn't take long for the sky to darken and lightning followed. Seeing this, Liu Bang's father came to the pond to take his mother home. When he came to the pond, he saw a dragon on Liu Bang's mother. Soon after, Liu Bang's mother was found pregnant and the child was Liu Bang.

In addition, after Wu Zetian was born, there were many visions of Taibai Venus during the day. What was the divination result of this vision? The hostess often?
