Zero risk or low risk, zero investment or low investment, high return. This is the only magic weapon for scammers to market their so-called "products" or other things, because if a person wants to do something with you, the most important thing is to be good. For example, if you give me 10 yuan, I can help you earn 100 yuan or even 1000 yuan. Any industry that can get high returns will be accompanied by high risks. No one makes money by throwing money into Qian Shengqian's cornucopia. Everyone has to pay.

A real company will invite you to talk at their office address, and will not invite you outside the company office.

4: I don't chase you down, and the black intermediary does the opposite.

When people lie, their eyes will unconsciously look up to the right.
