What is the story of Yiya's killing the son and offering the king?

Allusions:

Huan Gong once said to Yiya, "It's a pity that I have tasted all the delicious food in the world, but I have never eaten human flesh." Huan Gong's remarks were an unintentional joke, but Yi Ya kept them in mind, intent on showing off his skills in order to win Huan Gong's favor. No matter how noble the monarch is, he must never eat the meat of death row prisoners and civilians. Later, when he saw his four-year-old son, he chose to use his son's meat.

At a luncheon, Huan Gong drank a small golden tripod of fresh and tender broth, never tasted it, and asked Yiya, "What kind of meat is this?" Yiya cried and said that it was her son's meat. In order to pray for the health of the monarch, he killed his son to offer sacrifices to his master. Duke Huan was very uncomfortable when he learned that it was Yiya's son's meat, but he was moved by Yiya's killing his son for his own food. He thought Yiya loved him more than his own flesh and blood, and from then on, Huan Gong favored Yiya.

Qi Huangong once said that he had never eaten human flesh, so Yiya cooked her son for Qi Huangong, gained the trust of Qi Huangong, and wanted to appoint him to replace Guan Zhong, who was dying. However, Guan Zhong believes: "People's love must not love their own son, and the son's forbearance will make him love you!" So for him, Qi Huangong dismissed him and Wei Kaifang and Li Diao, and they were never allowed in again. In the end, Qi Huangong didn't listen to Guan Zhong's last words, but trusted Yi Ya and Vertical Carving. Qi Huangong was seriously ill, and Yi Ya made an insurrection with vertical Diao, filling the palace gate and building a high wall, which was blocked from inside and outside. Finally, Qi Huangong died of hunger.

Yi Ya, a famous chef in the Spring and Autumn Period, also wrote Elegance. He is the most popular minister and the most harmonious person in Qi Huangong. Yiya was the first chef to cook with harmony. He is good at seasoning and cooking.

As a young man, Yi Ya is good at seasoning, so he is very popular in Qi Huangong. Because he is a chef, a good cook and the first person to open a private restaurant, he is called the founder by the chefs.

First, Yiya found that her hands would be tickled by sweet potato skin when peeling it. He finally found a way to relieve itching through many practices: first take a bite, chew it, and then peel the sweet potato, so that it won't itch again.

Secondly, there is a famous dish called mutton with fish belly, which is also a famous dish in Shandong Province. According to legend, it was created by Yiya (actually, the fish hidden by sheep was created by Peng Zu, and Yiya asked Peng Zu for advice before coming to Shandong cuisine). Carp is the freshest aquatic product in the north, and mutton is the freshest meat. This dish is both fresh and compatible. Pickled vegetables are smooth in color, crisp outside and tender inside, and delicious. We notice that the word "fresh" is composed of "fish" and "sheep". It is said that Yiya hid mutton in the belly of a famous dish and created vivid characters.

Thirdly, Yiya combines cooking and medical treatment to create delicious food and convalescent dishes. Once, I was often ill, and Yiya sent me diet food. After eating it, I recovered, and Yiya was deeply appreciated by Hehe Chang.
