You are from a computer background and have a certain computer foundation. Then you can do computer training or computer maintenance while doing Internet cafes. These are your strengths. The computer is very expensive when you buy it now, but it will be worthless if you use it for one minute after buying it. Or you can rent them. If there are many rental houses there, they can be rented, so they can be rented. However, I suggest you communicate and coordinate with the landlord who rents the house, so as to kill several birds with one stone.
