"Forced Order" tells the story that the servant of Princess Populus euphratica, the sister of Liu Xiu, Emperor Guangwu of the Eastern Han Dynasty, hid in Princess Populus euphratica's home after killing, and Dong Xuan executed the servant while the princess was out. Princess Huyang tried to overwhelm Dong Xuan with the strength of her younger brother Guangwudi, but Dong Xuan didn't buy it. She argued in front of the emperor, insisted on principles, refused to admit her mistake against her will, and was sealed as an "injunction" by Emperor Guangwu.

The court appointed Dong Xuan as the county magistrate of Luoyang. At that time, Princess Huyang's servant committed murder during the day, because officials hiding in the princess's house could not catch him. When Princess Populus euphratica went out, she took this murderous slave as a companion.

Dong Xuan waited for Princess Populus euphratica in the mansion pavilion, stopped the princess's car, stopped the princess's horse, scratched the ground with a knife, loudly listed the princess's fault, reprimanded the slave and killed him. Princess Huyang immediately returned to the palace and told Emperor Guangwu Liu Xiu. Guangwudi was furious, summoned Dong Xuan and beat him with a stick.

Dong Xuan kowtowed and said, "Before I die, I just want to say one word." Emperor Guangwu said, "What do you want to say?" Dong Xuan said, "Your Majesty revived the Han Dynasty with virtue, but allowed slaves to kill good people. How will you rule the world? I don't need a stick, please let me kill myself. " I hit my head on the post and my face was covered with blood.

The emperor ordered Xiaohuangmen to catch him and make Dong Xuan kowtow to the princess to apologize. Dong Xuan refused, and Xiao Huangmen (referring to eunuchs in general) forced him to kowtow, but he refused to put his head in his hands.

The princess said: "When Uncle Wen was a common people, he hid fugitives and people who committed capital crimes, and the government did not dare to come to the door to arrest him. Since you are the son of heaven, can't your authority be imposed on a county magistrate? "

Guangwudi smiled and said, "The son of heaven can't be like the people." He ordered the stubborn county magistrate to go out. Dong Xuan was given 300,000 yuan, and Dong Xuanquan gave it to his officials. From then on, Dong Xuan attacked the strongman, and no one was shocked and trembling. The capital called him "Crouching Tiger, Hidden Dragon" and praised him: "Before Dong Xuanya, no one beat drums."
