This is a scam. At first, he will talk to you about your favorite topic and try his best to let you represent him. Later, I dragged you into the team they formed and lied to you with some plagiarized content. At first I thought it was true, but gradually if you don't follow his method, he will kick you out and sell you the tutorial. I am one of the victims. 298 yuan can't do anything, but think about what they are doing. I hope all friends who can see it are cautious.
