Why do we have a sense of ceremony when celebrating festivals?

The association of cultural symbols is related to the social group orientation of human beings to the objective world, so this "sense of ritual" is actually a subjective idea.

This kind of thing beyond the objective function of things can make completely independent individuals have the same topics and beliefs, thus forming a huge human society.

Most ceremonies have group attributes, such as weddings, swearing-in ceremonies and opening ceremonies. It is not so easy to get a group of people together, but if it is done, participants will feel that they have a bond with this ceremony and urge them to do something.

The existing human beings have a sense of ritual, which is also the result of evolution. Prehistoric humans who had no gossip nature and cultivated a sense of ritual were killed because they could not unite into social groups. Those who survived were descendants of our gossip king.
