2. When using it in the north, avoid close to the heating equipment, put it back in the piano box in time after use, and zip up the piano box.

3. In the wet season, one or two small bamboo charcoal bags can be placed in the piano box to absorb moisture and prevent mildew. In the dry season or in areas with dry climate, you can put a wet paper towel in the erhu box and replace it when the paper towel is free of moisture.

4. In order to better protect the piano skin, the loose string method can be used to reduce the pressure of the piano code on the piano skin, or the special top string code can be used to relieve the pressure of the piano code on the piano skin and prolong the service life.

5. The strings should be wiped regularly, one is to clean up the rosin scale, and the other is to clean up the sweat stains.
