Many people use WeChat with a girl's avatar for WeChat tripartite marketing. After chatting with you for a while, they indirectly tell you how she does foreign exchange trading, how to make money and how to relax. Then they recommend you a foreign exchange analyst and ask you to add him.

In fact, it is very likely that this "girl" and this "foreign exchange analyst" are both the same person or playing together, especially since this "girl" is a man.
