No ports except 80 are opened. What should I do?

Question

Computer networks

Hello, today I tried to open ports and could, but only 80 (and I need others). I tried to open 443,1080,7777,8888,8001 and many others but none of them opened. What should I do and what is the problem?

Dishman's China, from the "price is the main thing" series.
How did you open it, how are you connected to the tyrnet, and what do you want from this unfortunate shack, intended for the undemanding YouTube consumer?
