Maybe there are some guides to setting qubes to anonymity so that the browser can’t recognize my time zone (so that it is different on different AppVMs)

Whonix timezone should not be changed, see:
Post-installation Security Advice

P.S. translate.google.com and so on are good at translating documentation, but can’t translate the forum (you can only see the navigation menu), is there any way to fix it?

Dunno.
Copy / paste text there.
