I have a friend who told me to go to Sanmenxia, ??which is a good tourist place, but I suspect she is doing a pyramid scheme.

Haha, I’m not trying to hit you. Your friend is in danger.

Sanmenxia is a den of pyramid schemes.

It’s actually not difficult to see through MLM. The key is to see if you have the intention. Since you are suspicious now, that’s good. Do you feel like you have more frequent contact with your friend recently than before? Do I have a "good impression" of you more than before? Do you have a strong desire for you to go there? Have you never or rarely asked him to help you find a job? If you answer yes to all of them, it must be a pyramid scheme.

If any of the answers are yes, it's worth further observation...
