Do not expose the bowstring to the sun, and do not choose cloudy days when ventilating, because cloudy days are more likely to be damp.

In an air-conditioned environment and an environment with low air humidity, there is a phenomenon of moisture collection on the bamboo board, and it is easy to burn the bamboo surface when it is dry and wet. Burning silk is unique to hard bamboo materials. 502 glue can be used to repair the burning wire, apply it on the surface of the burning wire, sand it with fine sand, fill the gap with the ground wood powder, and then apply 502 glue, after several repetitions, the burning wire can no longer be seen, hard The wood has good plasticity. The finer the sandpaper, the better, the finer the sandpaper, the brighter it will be. Before waxing, the range of sanding can be wider, so that it will be more integrated with the surrounding area, and then use a dry cloth to coat the surface. Wipe the surface of the wax quickly until the light comes out, so that the burnt wire can be repaired.

This method is suitable for damaged parts of the appearance, etc. Wire burns and small cracks will not affect the sound of the bow, and can be repaired by using the method of repairing the burnt wire. After getting wet, it will be tight, which is a normal phenomenon, so in general, after using the bow, put it in a cloth cover or a piano box to prevent the influence of humid climate.

If you find the phenomenon of slumping skin, you can place the bow in a ventilated place to restore the original tightness, and must not be exposed to sunlight. However, you should also pay attention to ventilation, do not ventilate on cloudy days, because the water content in the air on cloudy days is larger, which makes it easier to get damp. When ventilating, it should not be too close to the ground. It is best to place the bow on a raised wooden board, at least half a meter away from the ground.

There is also a gap at the end of the bow. Most of this phenomenon is because the bow is shrinking to adapt to the surrounding climate, and the gap is pushed out. When repairing, just repair it carefully, and then press it again. After repairing, it is completely the same as the new one. the same.
