It is warm and humid in Minnan of Fujian Province, which is a heaven for all species of snakes. If there's a snake appearing in someone's home, they can't beat it to death, because the snake is believed to be a peace patroller sent by the family's ancestors. Any household having a snake entering the home is believed to live a peaceful life in the time to come. If anyone sees several snakes intertwining with each other by the roadside, the person is supposed to tear off a button and throw it away as a way of showing repentance. And the person should act as if he or she has not seen it. It is said that the snakes are mating and anyone sees it is considered going against all the heavenly laws of morality.
