Someone downstairs in my house put three chopsticks and a bowl at the entrance of the fourth floor. What do you mean?

Maybe something unclean came into the house. This French way is to send away ghosts and hope that the soul can be comforted. Three chopsticks are equivalent to three incense sticks, and a bowl of water is equivalent to rice under incense sticks for ancestor worship. Some people pray to send their ancestors away, hoping not to disturb the lives of future generations.
