How can I find a person surfing the Internet in that Internet cafe?

The easiest way is to install a version of qq20 10, chat with him, and you can display his ip. If the ip library is accurate, you can directly name the Internet cafe. If not, Baidu will search ip. The first one is to check the website where ip is located. You can usually find it. The first one was not found in Baidu search results, and the second one was not found. Anyway, you know which internet cafe this ip can be found in.
