How can I know if the dance training class is a liar?

First of all, it depends on the business license of the training center, whether it is a formal dance training center, and the dance studio design of a good dance training center is generally better.

Look at the qualifications of the coach. The most important thing is to see how they teach, whether they can teach with peace of mind and whether they can correct their movements when teaching, because some places will invite several coaches at random to teach, and it depends on the original students' learning situation and their comments. Good dance training centers are not promoted by them.
