There was a well-known figure in the Qin Dynasty named Lao Ai. Lao Ai was originally a small restaurant owner in Lv Buwei. He often performs with his penis. He put his penis on the bearing of the wheel, then turned the wheel and performed all kinds of unimaginable performances. Later, Lv Buwei gave it to Ying Zheng's mother, Evonne, who was the empress dowager as a eunuch at that time. Actually, Ed didn't clean it himself. LaoYi became the head of Zhao Ji, and rose all the way. Finally, he was crowned with a long letter. When Ying Zheng left Xianyang at the age of 22 and went to Yongcheng to hold a pro-government ceremony, Lao Ai rebelled in Xianyang and was finally killed by Ying Zheng. The two illegitimate children born to Lao Ai and Empress Evonne were also put in a basket by Ying Zheng and hung on the tower with a rope. Then the rope basket was cut, and the two children fell from the tower and died. The Empress Dowager Zhao Ji was exiled by Ying Zheng, and finally Ying Zheng recalled the Empress Dowager at the suggestion of the minister. Lv Buwei, the prime minister, was also implicated in sending Laoyi to the palace and was banished back to Luoyang. Later, on the way, Ying Zheng ordered Lv Buwei not to return to Luoyang, but to go to Bashu. At that time, Bashu only entered the barren land, so Lv Buwei committed suicide by taking poison.
