Duke Heng of Qi, formerly known as Gongzi Xiaobai, was the leader of the Five Hegemons of the Spring and Autumn Period.

Before he came to the throne, Guan Zhong shot Qi Henggong with an arrow, but Qi Henggong pretended to be dead and escaped.

After Duke Heng of Qi came to the throne, he imprisoned Guan Zhong and wanted to kill him, but Bao Shuya stopped him and advised Duke Heng of Qi that Guan Zhong could be appointed. So he took Guan Zhong back to Qi regardless of his past grudges. After talking with him, he felt that Guan Zhong was very talented.

, so he was appointed to handle important matters. Finally, Duke Heng of Qi made Guan Zhong the prime minister and jointly managed the government.

Before Guan Zhong died, Qi Henggong asked Guan Zhong who could replace him. Guan Zhong rejected the three people Qi Henggong said he wanted to use.

However, after Guan Zhong's death, Qi Henggong did not listen to Guan Zhong's opinions and still reused these three people.

These three people are Yi Ya, Kai Fang and Shu Diao.

Yi Ya was the royal chef of the palace and knew the taste of Duke Heng of Qi. Just because Duke Heng of Qi wanted to eat human flesh, he actually killed his own son to cook delicious food for him. Duke Heng of Qi was very moved when he found out.

Kai Fang was the prince of Wei, and he was very likely to become the emperor, but he insisted on working hard outside and never returned home. He stayed with Duke Huan of Qi for decades without returning home. Duke Heng of Qi felt that he was very loyal.

Shu Diao, in order to be able to stay with Qi Henggong, he actually committed suicide in the palace, which moved Qi Henggong very much.

Duke Huan of Qi himself was not outstanding in talent, and his policies on governing the country were not very good, but he had the ability to lead.

Therefore, Guan Zhong was able to govern Qi very well during his lifetime.

Those three people were expelled by Bao Shuya, but were later found by Duke Huan of Qi.

This left trouble for Qi's demise.

Because these three people were villains, they made Qi very corrupt when they controlled the government.

In the end, after Qi Henggong became seriously ill, he ignored him and didn't even know he was dead.
