First, read the English article below.

You can do this on a Windows computer or on a Mac computer. Once you've opened the "hosts" file and are ready to enter an address, proceed. Type in 127.0.0.1 and press the Tab ↹ key, then type in youtube.com and press ↵ Enter. If you use Chrome, you'll need to place a space after YouTube's address and then type in www.youtube.com there. Type in 127.0.0.1 again and press the Tab ↹ key, then type in m.youtube.com and press ↵ Enter. Again, if you're using Google Chrome, you'll need to add a space and the "www" version of YouTube's website here as well. Do the following:   Windows — Click File, click Save As..., click Text Documents, click All Files in the drop-down menu, click the "hosts" file, click Save, and click Yes when prompted.  Mac — Press Control+X (not ⌘ Command+X), press Y when prompted, and press ⏎ Return. Once you've edited the "hosts" file, it's best to restart your computer to ensure that the changes take place:   Windows — Click Start, click Power, and click Restart.  Mac — Click the Apple menu, click Restart..., and click Restart when prompted.
