Teach you how to register a top-level domain for free

Free registration for top-level domains, after going in, just click on the blue link twice to register. However, there is a condition: you must click on their ads. It's very simple, just randomly click a few blue links, and finally, as long as you open a website, you can register (note that you need to open a new website). Once you've clicked and opened a new website, log in again, and the registration page will appear. Good luck to you.
