Sacrifices have Zhaomu, which is to distinguish the order of father and son, distance, elder and younger, and closeness without disorder. Therefore, when there is an event in the Grand Temple, all the Zhaomu and Mu are present without losing their order. This is called the killing of closeness and distance. In ancient times, the king who knew the title of virtue and the salary of merit must be granted in the Grand Temple to show that he dare not monopolize. Therefore, on the day of the sacrifice, after one offering, the king descends and stands on the south of the steps of the east, facing south. The person who orders faces north, and the historian from the king's right holds the tablet and orders. He bows twice and kowtows. He receives the book and returns, and leaves the offering in his temple. This is the granting of titles and rewards. The king rolls up his crown and stands on the east, and the lady stands in the east room with a second veil. The lady offers the beans and holds the school, and holds the wine and gives it to the stirrup. When offering wine to a corpse, the wife holds the handle, and when receiving the corpse, the wife holds the foot. When a husband and wife give wine to each other, they do not take each other's place. When offering wine to each other, the wine must be exchanged. This is to make it clear that the husband and wife are different. When making a sacrifice, the bones are the main thing. Bones are of different ranks. The Yin people valued the thigh, the Zhou people valued the shoulder, and the front is more valuable than the back. The sacrifice is to make it clear that sacrifices must be benevolent. Therefore, the noble use noble bones, and the humble use humble bones. The noble are not heavy, and the humble are not empty, which shows equality. When benevolence is equal, politics will be carried out, politics will be carried out, and when things are accomplished, achievements will be made. The reason why achievements are made must not be unknown. The sacrifice is to make it clear that benevolence must be equal. A good politician does this, so it is said that the equality of politics and affairs can be seen here.
