2. Players first go straight from the door of the study room to the right, open the story in the first picture, and plug the firecrackers they obtained before into the gap.
There is another picture on the right of the first picture, and the second picture is covered with firecrackers.
4. Light the second painting and then hide in the cupboard and wait for the ghost to come (the explosion will attract the ghost).
Go to the teahouse and get a basin to put out the fire. After the fire goes out, enter the room and open the cabinet to get the red copper key five.
