Another way is that you can go to the office of the Music Department of Putian University to inquire, or directly consult the building management of the piano building, but generally speaking, the straight road is blocked, and the piano rooms are all allocated, so you can't run in for no reason.
That's it. It's easier to practice in a musical instrument store. I don't know exactly which musical instrument store it is, but my students practice in a musical instrument store, which proves that Putian still has musical instruments to provide piano practice.
