How about the lecture hall of Puyi Guo Xue?

The teachers of Puyi Guo Xue Lecture Hall publicize that their classes can achieve the purpose of self-examination, seeing the geomantic omen of Yangzhai, and divining to solve problems. It is also said that there is no follow-up fee, unlimited lectures and free resumption of classes, which makes you think that you can always learn things as long as you study hard and listen to several rounds. In fact, you can't talk much about these classes. You have been recruiting students and circulating basic white classes. There is no paper material, but if you want paper courseware, you need 400 yuan. And there is no service hotline. If you want to talk to them, you can only call them or virtual dial.
