In spring, Yingong was going to Tangdi to watch the fishermen fishing. Zang Qibo said, "If articles can't be used for sacrifices, military affairs, etc., or materials can't be used to make ceremonies and weapons, then the monarch should not touch them personally. A monarch is a person who leads people to social norms and codes of conduct. Therefore, the major events of the seminar are measured by the criterion of law, which is called "track". It is called "object" that materials are selected to make objects to display their cultural colors. Things that do not conform to the rules are called disorderly government. This is the reason why it failed. Therefore, hunting activities in spring, summer, autumn and winter are carried out in the idle season of agriculture, and military training (taking this opportunity). Every three years, the army should be restored when it returns home. They should go to the temple for sacrifices, feasts and celebrations, and count military objects and prey. In carrying out these activities, we should (make the carriages, horses, costumes, banners, etc.) have bright and colorful culture, distinct nobility and lowness, well-ranked and orderly growth: these are the prestige of lecturing on important events! The meat of birds and animals can not be put into sacrificial utensils, and the leather, teeth, bone horns and feathers can not be used to make military utensils. Such birds and animals, the monarch will not shoot them. This is from ancient times. Since the rules ah! As for the property of mountains, forests, rivers and rivers, and the materials of general utensils, these are all things that the servants are busy with, and that the officials are to be managed according to their duties, rather than what the monarch should be involved in. Yingong said, "I'm going to visit there." So he went to Tangdi and asked the fisherman to put out all kinds of fishing gear for fishing. He watched it there. Cen Botui said he was ill and did not go with him. "Spring and Autumn" said: "Yingong in Tangdi display fishing gear." It's not polite, and he goes far away from the capital.
