Why do so many people believe some liars who call themselves masters?

Some people have ulterior motives, such as Qigong master Wang Lin. In fact, his most important identity is an important part of China's social network. If you want to make friends with those dignitaries, introducing them is the most effective way. He has a wide network of contacts in powerful circles, which is why he has made so many star businessmen and officials. I think it is one thing for those people to believe in his Qigong, and the most important thing is to rely on him to know and make friends with others.
