What is the concept of sacrifice in Zhou Dynasty?

The religion of Zhou people is similar to that of merchants, mainly including: worshipping God, ancestors, ghosts and gods, divining and asking questions, etc. Zhou people worshipped God and ancestors. They believe that the souls of their ancestors are around God, and sometimes they come into this world to look after their descendants. Ghosts and gods mainly include the gods of the sun, the moon and the stars, the gods of mountains and rivers, the gods of the land and the gods of the valley. In Zhou people's beliefs, most of these gods were gods given by God. For example, the Valley God of Zhou people originated from Hou Ji, the tenant of Zhou people. The religious belief of Zhou people is far less than that of businessmen. They think that people's fate comes from providence, but they doubt God and think it is not credible. Although I have great respect for my ancestors, I will also swear when I am in pain, and even scold my ancestors, such as "ancestors and bandits."

Zhou people paid more attention to the sacrifices of heaven and earth, mountains and rivers and countries. The ceremony of offering sacrifices to the gods is called Suburb Sacrifice, which is presided over by Zhou Wang. It seems that God doesn't communicate with ordinary people. Other gods, such as land gods and valley gods, directly preside over human affairs, such as fertile soil and good harvest. The land god is also called the club, the valley god is also called the millet, and the place where the gods of the country are sacrificed is also called the club and the millet. A social sacrifice competition is held every spring. The society of Shang adherents is called Millie society. There are many gods in nature who are possessed by wizards and communicate with people. People also think that wizards are familiar with the past and the future and respect them very much. Even princes have sacrifices. Please adopt!
