Brother, use your brain and think about it, first: Does he have the ability to manipulate the column team of "China Central Channel 10"? Is CCTV 10 a fool? No inspection and verification? Second, even without investigation and verification, is I Love Inventing an advertisement? No, it's a column. Third, how much can you get by defrauding the training fees? If it were me, I would simply defraud you of the machine money, that would be great, or a deposit would be fine. Besides, no matter where you go now, there is no charge to register or study. I serve you for free, and I won’t let you see my patent. It's ridiculous that you overthrow yourself with your own words!
