It is reasonable to charge more than 2000 yuan for a course, and then after you place an order, the sales should continue to follow up and let you buy as many courses as possible. In this way, you can figure out how much the cost of manpower and material resources will be. In the future, if you want a refund, you have to have customer service to accompany you to "play Tai Chi". Therefore, it is reasonable to charge more.

As for whether it is effective or not, first of all, the teaching teacher is really professional, but the evaluation teacher is a temporary person, and then it is basically false to apply it directly. Anyway, reporting is not a matter of opinion.
