What would you do if a net friend you have known for three years invited you to travel together?

I think it's better not to go out to meet, because the network is a virtual world. Just because you chat with a netizen doesn't mean that you really don't know him, because you don't have enough contact time, and your personal safety should be put first. But you have known the netizen for a long time and have a certain understanding of his daily life. You can consider meeting and bringing your good friends, which will be safer.
