Maintenance method

You can't be exposed to the sun. Exposure to the sun for a long time will lead to wood cracking, which is a very serious problem. Once the piano body cracks, it is basically scrapped, so it should be placed in a place where it can't be exposed to the sun.

Don't put it on the ground if there is floor heating; Don't put it in the car for a long time in summer; If you play outdoors or stay for a long time in winter, it is best to keep the piano away from the heat source after entering the warm room, and let it gradually heat up to avoid the piano body heating up rapidly.

Don't put the guitar in a place or space that is too wet. Make sure that the bag with the guitar is dry. Don't expose the guitar to the sun. Don't put the guitar near the heating.

If the room is humid, buy a bag of desiccant and put it in the resonance box of the guitar, but it is better to find a more suitable place to put the guitar. The weather in the north is mostly dry. If there is no humidifying tool, you can also put a basin of water near the piano by indigenous method, but not too close, but moderately. Pay attention to this problem because dampness or dryness will cause deformation of the guitar neck or cracking of the panel.
