How did the coup of Empress Huayang in Daqin Mansion fail?

Some courtiers of Chu who were dissatisfied with Queen Huayang and the imperial clan forces of Qin conspired to suppress Queen Huayang in the name of the King of Qin. The son that Empress Huayang wanted to push was the King of Qin, who was imprisoned by him, and the Mi forces were bloodied. In order to sit on the throne, Qin Gui, far away from Zhao, recognized Empress Huayang as his mother and gave her a name. With the help of Empress Huayang, he took the position of King Qin as his son. Queen Huayang is not a good person, she only does good things. All she wants is a king who obeys her kindness. After Ann's death, the Qin people succeeded to the throne, and Queen Huayang became the Regent's Queen Mother, presiding over the state affairs.

How can Zi Chu, who has become the king of Qin, obey the wishes of Queen Huayang and disobey the orders of Queen Huayang many times in the court? In particular, he wants his son A Zheng to be a prince. This move greatly angered Queen Huayang. In the face of a chess piece that doesn't listen to yourself, you have to abandon it. So Queen Huayang promoted the coup and wanted to support a more obedient puppet. Cheng Jiao's son became the first choice. During the coup, Empress Huayang and Yang Quanjun took control of Xianyang capital and sent people to assassinate Qin aliens, whose safety was threatened instantly. After learning the news, they immediately joined the ministers to discuss the rescue of Qin Gui, and Ying Zheng and Fan rode to the capital to rescue him, pleading with Zhang Taigong to save him. Then Ying Zheng came to kill the treacherous court official, Qin barbarian was saved, and the coup of Queen Huayang failed.

In fact, the failure of this coup seems doomed. Cheng Jiao has no king's heart, and Yangquan Jun has no leader's talent. Empress Huayang can only rely on the strength of Mi surname in Chu system, which is not a long-term and powerful support, so failure is not unexpected, but the ambition of Empress Huayang has not died from now on. There are more or less some factors behind the meeting between Yan Hua and Ying Zheng, but what about troubled times? If you have questions, please leave a comment below. Thank you for your support!
