Double pupils are actually eye lesions. Why is there such a legend? Kings or saints who just happen to spread, or some celebrities who have made great achievements, are all primary school students.
In fact, people who have such eyes are not gifted, but myths, which are also related to the ancient cultural and social environment. There are eight famous people in history who have such eyes. They are:, Shun, Xiang Yu,, Yu Kan and Li Yu. Some names are familiar. If you don't check them on purpose, I'm afraid you don't know Xiang Yu, Li Yu and binocular. Among these eight people, some are kings and some are saints, but only the general (Yu Juluo). And most of them died ugly, either beheaded, committed suicide or poisoned ... only a few people died of natural causes.
In the folk, there are also many eye diseases, but because ancient people were superstitious, there were phenomena that were different from ordinary people and could not be explained and understood at that time, which would be considered Uber. Either they are alienated, squeezed out and bullied by everyone, or they are executed by local people as demons.
People still have heavy pupils and don't need others to deal with them. When their parents saw such eyes, they were probably drowned or abandoned at birth. No matter how lucky the growth is, if it is seen by local officials, it is estimated that it will be quietly disposed of. Because, after all, people in ancient times believed in this legend, just like some people who had potential threats to the imperial power, they would clean it up.
