Dressed as He Xiao, the son of He Yan, the consort of the Wei Dynasty, he followed his parents into the palace for a banquet at the Tai Chi Hall just after the winter solstice. Princess Jinxiang urged him to get married in the car, but He Yan interrupted and was yelled at. He Xiao lowered his head and looked at his outfit - the son of He Yan, the grandson of Cao Cao, and the cousin of the current emperor Cao Rui. With this status, he can walk sideways in the court. But the history books told him that He Yan would be killed by Sima Yi in a few years. The carriage bells jingled, and the cornices of Taiji Hall could already be seen. This time before entering the palace, we must first find out the background of the Sima family.
