There are countless emperors who have been green in history. Because of the complicated royal relationship, an emperor will have more than one cuckold husband. Of course, when they are greening others, others are greening them. Sometimes green comes and goes, sons turn green to their fathers, and fathers turn green to their sons. Whether it is the relationship between uncle and nephew or the relationship between brothers, this is inevitable.

Li Shimin and Li Zhi? They are father and son soldiers. There is no denying that Li Shimin is a generation of wise men, but his style is not pleasing. First he had an affair with his uncle's wife, and then he raped his uncle's daughter. Even his brother Yuanji's wife was spared. However, in his later years, his favorite Wu Cairen had an affair with his son, which made him the biggest cuckold.

Li Zhi is worse than his father. First he beat his father into a turtle before he died, and then he became his brother-in-law. But he afforested Wu Cairen, which his father got, and eventually became an emperor. He also found Toy Boy, so there are countless green hats on his head, but those who are green are nobody, so he won't count them.

Yang Guang can be said to be the most cuckolded emperor. ? He was harsh on the people, and the people were miserable, which led to many riots. He can be called a tyrant. He wore a cuckold for his father and brother before his death, but after his death, his queen Xiao Huanghou became the favorite concubine of many kings, even the concubine of others, and later became Zhao Rong in Li Shimin Palace of Emperor Taizong, wearing five bright cuckolds on her head.
