Why was Sima Yao, the dutiful son of Jin Dynasty, killed by his favorite concubine?

Because he was drunk, he told the princess that she was too old to stay in the palace. If she hadn't given birth to a son and a half daughters, she wouldn't even have to be a nobleman in the end. The princess was very angry after hearing this, so she withdrew all the attendants and handmaids around her and secretly killed Sima Yao. The princess did this for a reason. At that time, the minister of the DPRK was also very dissatisfied with Sima Yao, and the princess thought that she was doing harm for the people. When Sima Yao was born, someone told him fortune-telling, saying that the golden throne was prosperous, and Sima Yao's nickname was prosperous, which meant that the Jin Dynasty would be destroyed by him. His father, Sima Yi, was afraid that Sima Yao would destroy the country. Before he died, he left his last words and made Constant Temperature the Regent, which bound Sima Yao's words and deeds. Later, the ambition of constant temperature was stifled, and Sima Yao began to expand without restraint. When Sima Yao was in office, the most famous battle was the Battle of Surabaya. In fact, Xie An was the greatest contributor to the Battle of Feishui, but Xie An was very powerful. Sima Yao wanted to take Xie An's power away from him, so he killed Xie An after he succeeded, so that he really held the power in his own hands, but this caused dissatisfaction among the DPRK ministers. Everyone knows that Xie An is the biggest contributor to this war, and so is Sima Yao. As can be seen from the Xie An incident, Sima Yao did not hesitate to hurt others or even kill others in order to achieve his own goals. Although Sima Yao achieved the goal of seizing power, he has been indulging in debauchery and debauchery in the course of his rule since then. Once he was drunk and told his concubine that she was old and had no children in the palace, and she would be driven out of the palace by herself sooner or later. The princess killed Sima Yao in a rage, and Sima Yao did it herself. If he doesn't respect others, he won't be respected by others.
