Where can I find high-quality guqin？

The external features of a guqin include the body, surface, shaft, and string axis. The body of a guqin is the main part, which can be divided into three types: long body, short body, and small body, with the long body being the mainstream. The visible part on the piano surface has seven string tracks and thirteen badges. The shaft refers to the axle used for the strings, and buyers need to check if it is in good condition and if there is excessive wear. The chord axis refers to the mechanical part used for tuning and also needs to be checked for completeness.
As a musical instrument, the guqin must be able to play. So not resisting fingers, not sanding, and not playing board are essential conditions for an excellent guqin. Then there is the sound. As an exercise, being able to produce a sound is basically enough to satisfy the practice, but as a good friend who accompanies the pianist, the timbre cannot be ignored because it directly relates to the cultivation of the interest of the pianist. A qualified guqin should have a consistent timbre and volume for its scattered, pressed, and overtones. The sound of a guqin should have a sinking feeling, and it is considered good if the sound is not scattered and the charm is long.
The production time of guqin: The first step is to make the body of the qin for about a week, and after completion, it should be left for at least 3 months. The second step is to wrap the cloth and apply the gray tire, which will last for about 7 days and be left for 1-3 months, depending on the weather (it may take longer due to natural dryness). The third step is to apply large paint, polish it over and over again, around March to December. This is manual painting, not the type of spray gun. So it takes at least 8 months for a normal handmade guqin to come out, and of course, pianists work in batches, as they spend a lot of time waiting. But what the factory produces is different. The chemical paint dries quickly and is uniformly cut. It can be made in 10 and a half days, but this will definitely not make a good piano.
