The worst museum I have ever visited is not like a museum at all, but more like a training institution, a warehouse with a facade to store the old house, and the piano can be played, and the sound has not been adjusted. It is terrible that a piano museum does not adjust the piano. It is really nothing to say that the buckets, rags, water bottles, wrapping paper, packaging boxes in the exhibition hall are scattered. A messy look like many old piano keys corroded and messed up. I look at the words that I feel sorry for introducing famous piano manufacturers. Living off like can't wait to do business, don't call it a museum, call the warehouse directly, lock the door, only for the people you want to show, is it not good? PS. Show 9 o'clock business, 9:50 to the door, the entrance and exit closed, no staff.
