1. Fooling students to sign up, promising a refund at any time, and later hacking students, this is cold violence.
2. Brainwashing is a successful course, and the course is repetitive. There is nothing substantial to learn. The more you listen to it, the more it expands, the more it floats, and the less it falls.
3. Bad world outlook and extremely bad personality, threatening to insult classmates, thinking that the whole world is sorry for itself, but not reflecting on its own problems.
4. Exaggerate and brag about yourself. In fact, there is nothing, it is all fake.
Business license, name and ID card are all fake, and there is no trust at all.
