Shenyang's musical instruments are concentrated in Hao San Street (in front of the Conservatory of Music), a path opposite the west gate of the Xinglong family in Zhongjie (the path between the small Shenyang Gome and the spring) and Taiyuan South Street. I don't know if there is a brand you want, so I suggest you come to the door. The musical instrument store in Taiyuan South Street mainly sells electronic organ and electroacoustic, and the musical instrument store in Hao San Street makes it easier to find the harmonica you want.
