In fact, it is not just WeChat payment. If you know a little about Tencent, you will find that many of Tencent's businesses rely on WeChat and QQ, and the game business is typical. With WeChat and QQ, Tencent has firmly grasped the entrance of the cmnet era, and it is natural to become today's Internet giant.
In fact, what I am curious about is why people are willing to involve money in a chat APP (WeChat and WeChat payment), but they just don't like to communicate on a payment software (Alipay and its social networking). There may be more reasons involved.
