Why does Guan Yu, a military commander, like to wear a cuckold?

Guan Yu's green hat is different from our green hat today.

It is said that when Liu and Liu became sworn, the clothes Liu Bei gave Guan Yu were green, so later Guan Yu wore a green hat to show his respect for his eldest brother. There is also a saying that Guan Yu was just a fugitive before he went to Liu Bei, and on the day he met Liu Bei, he wore green clothes, so Guan Yu later wore green clothes and a green hat to commemorate that day. Therefore, Guan Yu always wore a green hat to show her identity when she first debuted. Besides, it is said that green also represents a person's solar terms, and Guan Yu's green hat can show his upright solar terms, but this is also a guess of future generations.

In fact, as descendants, we don't know what color hat Guan Yu wore at the beginning, or even whether he wore a hat. Now most TV dramas depict Guan Yu wearing a green hat, mostly from some statues handed down from ancient times.

In fact, Guan Yu used to be a cuckold. Maybe he just found a green hat and brought it with him. Maybe Guan Yu likes cuckoldry. After all, the meaning of the cuckold at that time was different from that of the so-called cuckold today. As descendants, we don't need to make too many meaningless speculations about Guan Yu's cuckold behavior.

In the Han dynasty, green was a color that only nobles could use. Perhaps Guan Yu wears a green hat just to represent Guan Yu's identity. But another possibility is that Guan Yu is a non-mainstream boy, so he wears a cuckold, right?
