What's the difference between WeChat qq Fetion?

Wechat has two functions: making friends nearby and voice messaging, which is very convenient to use on mobile devices, but useless on personal computers. QQ is a cross-platform software. In order to ensure cross-platform, various platforms are not allowed to add new modules at will. In addition, WeChat can be used as a new business growth point. For example, Tencent has two points to make money, and it will not give up a little without damaging customer satisfaction.

The relationship with Fetion is far away. First of all, Fetion is a mobile company, aiming to compete with Tencent for the share of instant messaging. Of course, the operation method is the same as QQ's method of expanding new business, and the vast user base is used to give certain discounts to attract employees. It is unrealistic to say that the purpose is to crowd out Tencent, but it is unrealistic to say that it can at least increase a business growth point and retain loyal users to a certain extent, because Unicom and Telecom have done a poor job in this respect.
