There are two pavilions in the Yuanzhuang Garden. Although I can't play the piano, I'm still interested in musical instruments. There are more than 100 pianos in the two libraries, covering a wide range of style manufacturers. They have lasted for more than 200 years. Some transparent pianos, corner pianos, etc., which have been discontinued for a long time, are quite rare, and can be seen here, which is quite worth seeing.
