Xie Yun disguised herself as a man and entered the court as an official, and was sent to the border to defend against the enemy's millions of troops. Her colleagues waited to see her joke, and the enemy general threatened to sacrifice her head to the flag. She raided food and grass at night, separated the enemy camp, and set up ambushes in valleys. The 30,000 remaining soldiers defeated the enemy army to a complete defeat. On the day when Banshi returned to court, the emperor was waiting for her on the tower - holding evidence that she had disguised herself as a man.
