First, it was found to have a good promotion function, and then it was quickly used as a channel to promote goods, and WeChat business came into being, including many relatives and friends. In order to increase traffic, they take the initiative to add friends, so everyone's WeChat friends are increasing, but these friends are just to promote products, not our real friends.

Secondly, the interface of WeChat looks more like an open platform, and some very private things are not safe to put on it, which makes people feel insecure. Without trust and respect, people have low dependence on it and will not make intimate friends on it.

Thirdly, it has many other additional functions, such as official WeChat account and applet, which makes it look even more confusing, and it is difficult for people to use it as a platform for exchanging ideas and communicating friendship.
