Historically, emperors have bowed to Cao Cao.
What's the point of being the last emperor? Poor emperor Liu Hanguang. I wonder if he anticipated the shame of his descendants? There is no question of whether it should be. Emperor Xian of Han Dynasty has only one emperor's name. The world belongs to the Cao family, and the minister is the minister of the Cao family. People only know that there is a prime minister Cao, but they don't know that there is an emperor Liu.
I'm here to find a fig leaf for Emperor Liu: all three daughters of Cao Cao were married to Emperor Han Xian, and Cao Jie became the queen. Cao Cao is the father-in-law of Emperor Liu, so he doesn't pay attention to the relationship between monarch and minister. Emperor Guangwu of Han Dynasty may have buried people with bad feng shui, so all short-lived puppets should not have dignity from their grandchildren.
