I Fix Air-Conditioner

The hearse with the weird odor slowed to a stop before the entrance. The sound of pebbles could be heard bouncing on the ceiling. There were footsteps coming from the corridor, and there seemed to be someone sawing next door. The door knob to the room rattled slightly, and the faucet in the bathroom kept dripping even though it had been screwed shut. There was a rubber ball that rolled on its own underneath the bed. Wet footsteps started to surface one after another on the floor. 
At 3 am, Chen Ge held a cleaver in his hand as he hid beside the room heater. The call he was trying to make was finally answered. "Landlord, is this what you meant by 'the house can be a little crowded at night'‽"

Both the girl and the woman's voice sounded quite normal, but after combining them with the strange environment and curious lyrics, everything took on a different meaning.

"The first part was sung by the girl. She was looking for her mother, and the latter part was probably sung by the mother. They were in the same room, but the daughter cannot see her mother, and the mother cannot reach out to touch her daughter; this can only mean that one of them must have died and transformed into a ghost." Wang Dan's analysis was sharp and to the point. His girlfriend was already shaking.

"This room is not safe either; we should leave."

"No." Wang Dan did not choose to leave like before but shook his head determinedly. "Before the voice of the woman and the girl came, did you hear the sound of a music box?"

"Music box?" Wang Dan's girlfriend was confused. "I think I did, but what does that have to do with us leaving?"
