I saw a snake when I demolished the house. What should I do with this snake?

Snakes like us in the house are generally not poisonous snakes. It doesn't hurt anyone, so just let him go. Traditionally, a snake is a little dragon. Like a god, it is unlucky to hurt it. Besides, in the case of tearing down houses and building new houses, you can't kill things indiscriminately. Just burn two pieces of paper and pray for peace.
