Anyway, it might be a problem if you know nothing about internet technology.
Right here right now, I could visit blogger.com and edit the blog, however visiting *.blogspot.com is impossible.
With custom host file, visiting google, youtube, voa and bbc is fine, with IPV6 proxies, facebook and twitter works great.
What I need is just a newest host file including IPV6 address of the blocked websites, which could help me throw proxies away.
HTTPS and IPV6 could also be blocked in theory, however, the blockade will become the tombstone of all the dictators, sooner or later.
