What on earth makes him like to wear a cuckold?

There are several sayings, some say it is to hide yourself, some say it is to warn yourself, and some say it is a personal hobby.

The first argument is that Guan Yu did business in the market before following Liu Bei and earned money by selling things to support himself. There was a time when Guan Yu bought dates, and then he found that the dates in the yard next door were growing well. To save money. Guan Yu stole people's dates and hid them in a green hat. Others say that this disguise is to disguise themselves in war. Just like soldiers wear camouflage clothes now.

The second theory is that this hat was given to Guan Yu by Liu Bei. It is said that Guan Yu likes a woman, but because Guan Yu is fighting outside all the year round, women can't stand her husband being away all the year round and running away with others. Liu Bei was worried that Guan Yu would affect the battle because of his womanhood, so he gave him a hat and warned him to distinguish between the important and the light. Moreover, Guan Yu has been wearing a cuckold in order to make himself firmly remember this shame.

The third argument is that Guan Yu's face is not very red. Guan Yu thinks wearing a green hat looks better. If he leads troops to fight, he can make his soldiers and enemies feel strong. It can not only give confidence to our own people, but also make the enemy feel deterred.

Of course, these are speculations of future generations. Maybe everyone's guess is wrong. The truest answer is also the simplest, just because Guan Yu likes green. After all, Guan Yu is the only one who knows the real reason. During the war, soldiers were not at home, so they had no time to choose clothes and wear what they liked.
