From a superstitious point of view, the appearance of snakes is not a bad thing! The appearance of snakes in reality is different from the concept of dreaming of snakes in The Duke of Zhou. There is a snake in your house. Don't hurt it. Guide it to a safe place where you can't see anyone. It won't hurt. It won't hurt.
On the other hand, having creatures living with you shows that your home is very suitable for survival. Very good! Everything is happy. Your home is a blessed land! Hehe, help him settle down. . . . . .
Although I am an atheist personally, I prefer the second explanation. Contradictions hahaha. . .
