At present, the comparison of guqin below 5000 is used as a practice piano. Of course, it is not that all pianos below 5000 are not good, but it is difficult to choose a piano suitable for long-term playing at this price. Guqin is a bit expensive now.

As for the musical instrument factory, it is like this. If you want to buy a piano for long-term performance, you'd better choose a hand-made piano (with seal and signature) instead of a piano mass-produced by a musical instrument factory.

I'm also in the north. I bought my piano long ago. One of my friends bought a piano in Beijing last year, and the other one bought it online (Tianyi Qincha). Their pianos are all very good.
