Insidious Investigator

Rong Jie studied folk customs. After studying for four years, I came to one conclusion: ghosts do not exist. After graduation, he went to City S to look for a job and checked into a haunted hotel on his first day. There was a knock on the door early in the morning, the TV turned on by itself, the bathtub faucet was tightened and still making noise - the other side of the bed slowly sank, and there was a human-shaped watermark on the sheets. Someone saved him. That person opened an "Old Customs Consulting Firm", and there were only two people in the entire firm: the boss and him. Paper figures, stand-ins, and first seven. The folk rituals in the textbooks that he dismantled as social phenomena turned out to be true. And every one of them is even more unreasonable than what is written in the textbook. He believes it now. But he also wanted to know: why they stayed here.
