First of all, there must be many Internet cafes before you, and there is fierce competition among them, playing the card of recharging and sending fees. Internet cafes that have just opened don't have so much capital to fight with them. After all, first of all, you have to withdraw funds.
Secondly, now that the material conditions are rich, many students have their own notebooks. There are a lot fewer students going out to surf the Internet than a few years ago, and it may be impossible to make money by opening an Internet cafe.
If you just want to open an Internet cafe, it will be a very difficult process. Good luck.
