There is a professional guzheng musical instrument store in Shenzhen called Hongyuefang, which is very famous on the Internet, but the reality is very poor. I'm a student there, and now I've been cheated out of getting my tuition back. The teacher keeps correcting it for me. I hope the landlord will do a good job, not as bad as the Red Crescent, and the treasure will be gone. I regret it now, but it will be a lesson.
