Will guqin crack when it is brought from the south to the north? How to prevent it?

It depends on your piano. Is it new? If the piano has just been finished and is in a hurry to be transported to the north, it's best to seal it for a while, or put it in the piano box after playing. The weather in the north is relatively dry, and the piano in the south can't stand it, and the paint on the piano surface is easy to crack. It's best to buy a bottle of Bellevue (yellow) cleaning instrument or white vaseline, and put it on after practicing the piano to protect the paint. Don't expose the guqin to the sun.
