The placement method is as follows:

1. Piano: The piano is placed in the living room or music room. You can choose to place it next to the sofa in the living room or next to the TV cabinet. It makes it easier to communicate with family or friends while playing the piano and enjoy music.

2. Air conditioner: The air conditioner is placed in the living room or bedroom. The most common location is above the TV cabinet. It can make the cold air from the air conditioner better spread to all corners of the room, providing a good cooling effect.

3. TV cabinet: The TV cabinet is placed in the center of the living room, where you can watch TV programs. The appropriate location can be selected according to the layout of the room and the placement of furniture to ensure the coordination and visual effect of the TV cabinet and other furniture.
