Late night funeral home, the seventh rule: at three o'clock in the morning, you must wear headphones and listen to the suona, otherwise you will hear the sound of your own death. On Qin Tinglei's first day at work, his earphones exploded. The whole mourning hall was silent for an instant, and hundreds of ghosts cried and howled for his life. They didn't know that he had been fed by dead people since he was a child, and there was a real evil spirit living in his body. When the Weirds tore up the rules and began to slaughter, Qin Tinglei smiled, squatted down and knocked on the coffin board: "Since you don't abide by the rules, my rules are much simpler - either kneel down and play the suona, or your soul will fly away."
