Bao Shu Ya said to his servant, "You can't say that! Guan Zhong's family is poor and he has to support his mother. It doesn't matter how much he takes. On one occasion, Guan Zhong and Bao went to war together. Every time they attack, Guan Zhong hides behind. Everyone scolds Guan Zhong and says, "Guan Zhong is a man who is afraid of death! Bao immediately spoke for Guan Zhong: "You misunderstood Guan Zhong. He is not afraid of death. He wants to take care of his old mother! Guan Zhong listened and said, "My parents gave birth to me, but Bao knows me! Later, the king of Qi died and his eldest grandson became king. They eat and drink every day and do nothing.

Soon after, the big prince was killed, and the state of Qi was really in chaos. Guan Zhong wants to kill Xiao Bai and make Xiao Bai king smoothly. Unfortunately, Guan Zhong missed the arrow when plotting against Xiaobai, and Xiaobai didn't die. Later, Bao He returned to Qi before Guan Zhonghe and became the King of Qi. When he became king, he decided to let Bao be the prime minister, but Bao said to him, "Guan Zhong is better than me in all aspects, so he should be invited to be the prime minister!"
