Isn't it good to add boys' WeChat on the train?
Not so good. I'm not sure whether this boy really makes friends or has other malice. In the era of mobile internet, some people use social networks and communication tools to cheat online from time to time. For your own safety and the protection of personal information, it is recommended that you do not easily add strangers' micro-signals or exchange communication tools in the network, public places or unfamiliar environments, and treat strangers with caution.
