Zi Chu died early, the young Ying Zheng came to the throne, and Lu Buwei controlled the government with the power of the prime minister. The influence of Guandong guest ministers and new aristocrats expanded in Xianyang, squeezing the power of the old clans in Qin. As the Queen Mother, Zhao Ji gradually developed profound conflicts with Ying Zheng over the ownership of royal power and the line of governing the country. In order to check and balance all parties in the court, Ying Zheng initially relied on the new nobles. Later, fearing the power of the Queen Mother, he moved Zhao Ji out of Xianyang and moved to the old capital Yongcheng - Yongcheng was the old capital of the Qin Dynasty and the basic base of the old clan.
As the leader of the clan, Ying Miao formed an alliance with Zhao Ji out of common political interests, and the two gave birth to two sons. The old clan group of Qin State secretly recognized these two children and planned to depose Ying Zheng if necessary and support the son of Ying Miao and Zhao Ji. Ying Mu served as the regent in Yongcheng as the "royal father". With the support of the clan's military force, he launched a long game of royal power with Ying Zheng and Lu Buwei of Xianyang.
