What are the descriptions of the idea when the monarch was born?

Many monarchs are born with hallucinations, and their descriptions are very exaggerated. However, some hallucinations are artificially compiled, giving the monarch magical colors, which makes people feel that this monarch is destined by heaven and is the real dragon emperor, which makes his subjects more convinced of the monarch and is conducive to the monarch's rule.

As we all know, Song Taizu Zhao Kuangyin was the founding emperor of the Song Dynasty. It is said that he had a unique fragrance when he was born. A few days after Zhao Kuangyin was born, his body was still red, and Zhao Kuangyin's skin was yellow. Anyway, it's strange.

When Cao Pi, the Emperor of Wei Wen, was born, it was said that there were seven colors of clouds in the sky that would never dissipate, so some people said that Cao Pi would make great achievements when he grew up.

When Zhu Yuanzhang, the Ming emperor, was born, he said that Zhu Yuanzhang's mother had a dream when she was born, and then dreamed that a fairy gave Zhu Yuanzhang's mother a magical elixir. Later, after Zhu Yuanzhang's mother gave birth to Zhu Yuanzhang, the room was full of red light, which was a natural sight.

When Emperor Liu Che of the Han Dynasty was born, it is said that Liu Che's father dreamed of a magical pig riding a red auspicious cloud to the place where Liu Che's mother lived. Then Liu Che was born soon. In the past, Liu Che's name was called Liuzhi, which means pig, which means that Liu Che is the reincarnation of auspicious pig.

Anyway, emperors have some magical legends more or less. Even without natural eyesight, historians will make up some magical experiences for them to make them more important in the eyes of ordinary people.
