Everyone wants to have wealth and status, but everyone should also cherish family ties and love. Even if you gain benefits by betraying your loved ones, because this value is not accepted by the world, it will be difficult to end well in the rejection of the world. In Chinese history, there were also some people who killed their relatives, but none of them got a good ending.

In the history of the Spring and Autumn Period, there was a famous Yi Ya, who was the chef of Duke Huan of Qi. It is said that Yi Ya's cooking skills were unparalleled in the world and he cooked countless delicacies for Duke Huan of Qi. Once, Duke Huan of Qi accidentally said to Yi Ya, I have tasted all the delicacies in the world in my life, but I have never eaten human flesh. But because of these words, Yi Ya killed his 4-year-old son, made meat soup from him, and dedicated it to Duke Huan of Qi.

Qi Henggong was very moved and thought that Yi Ya was loyal to him and a trustworthy person. Later, Guan Zhong, the Prime Minister of Duke Huan of Qi, became seriously ill. Duke Huan of Qi asked Guan Zhong who could take his place. Instead, Guan Zhong asked Duke Huan of Qi, who do you think is the most suitable to be the prime minister. Qi Huangong said, "How about Yi Ya?"

Guan Zhong said, Your Majesty, you have tasted all the delicacies in the world, but the only thing you have not eaten is human flesh. Yi Ya killed his son and made broth and presented it to you in order to please you. A person who can even kill his own son is inhumane. A person who doesn't even love his own son, who else do you think he will love? If you want to reuse him, Qi will definitely fall into chaos.

After Guan Zhong died, Duke Huan of Qi still chose to reuse Yi Ya. One time, Duke Heng of Qi was away from the country for a vacation. Yi Ya took the opportunity to launch a palace coup in the country and wanted to make Duke Heng of Qi's youngest son the king. Duke Heng of Qi rushed back to quell the rebellion, but was besieged by the rebels in the palace. Duke Huan of Qi starved to death three months later.
