I often get calls from Beijing saying that I want to ask Wu Gong what new scam this is.

At first, I thought of a joke. The difference between anger, anger, madness and dumbfounding?

If it is understood as a scam, it should not be a new scam. First, find a martial arts frequently, and then you should be eager to say what you have in your hands and buy it at a high price. When you get used to it, it's time for a martial artist to call you and ask if anyone is looking for him and what he has to sell you cheaply.
