You're right. Don't go to that place to learn dance. You must go to a professional dance school. I know a place that teaches well. Ask. The address is at Room 10 1003, Paris Spring, Hongqi Street. They are all small classes, with no more than 15 students in each class. The tuition fee is not high, and the teacher teaches it by hand. You can search for "Junhui Dance" in Baidu.
