Where can I learn authentic Xingyiquan in Shanghai? How much is the tuition?

In fact, there are still many places to learn Xingyiquan in Shanghai, and there is one in Pudong, but it belongs to the nature of fitness and learns to play. Another one may be far away from you, in Chen Xing, but the teacher there lives in Xuhui District, Puxi, and Chen Xing is his hometown, so he came back to teach boxing. Besides, there are classes only on Saturday. Usually, the teacher has been practicing by himself in Jian Kang Park, and his students occasionally visit him. His name is Wang Senlin, and his teacher Deng Fuxin is an internationally renowned martial arts teacher. But he is in Dominica all the year round, and few people in China know about it except some insiders. Wang Senlin is too old to know about packaging, so no one knows. You can go to the park to find him at four or five in the afternoon. He taught China people not to accept money.
