Zhongshan Park Guzheng Vocal Music Training Enrollment Class is at the entrance of Zhongshan Park (Metro Lines 2, 3 and 4). Older people can also sign up there. PS: No.31165438 Lane 3 12, Yuyuan Road, Changning Campus of Shanghai University for Senior Citizens (I wonder if there is a guzheng class).

It's never too old to learn. I hope I can help you.
