Empress Wu Zetian of the Tang Dynasty (AD 655), Tang Gaozong was unable to handle political affairs because of frequent headaches and dizziness. Physician Zhang Wenzhong said: "If the evil wind rushes up, it is necessary to puncture the blood in the head before it can be cured."

Although Wu Hou is a woman, she is ambitious and wants to be the king of a country and govern the world. So she hoped in her heart that the emperor was dying, so that she could monopolize the power. Of course, she didn't want the emperor's illness to be cured, so she pretended to be angry and said, "The physician will behead him. How can you acupuncture and replenish blood for the health of the emperor? "

Zhang Wenzhong, a doctor, immediately kowtowed and begged for his life.

Gao Zong said: "Doctors are talking about diseases. How can they blame them? And I can't stand the headache and dizziness, so let him treat me! "

The doctor was ordered to repeatedly needle Gao Zong's head. Gao Zong suddenly said, "My eyes have seen it."

Before the words were finished, Wuhou bowed down in the curtain and thanked him: "God gave me a good doctor." He took out the silk treasure to the physician, which shows that Wu Zetian is so treacherous and fickle.
