It sounds like Tor faces the most serious problems in China. I'm wondering how Tor (Tor Browser) is working in China now: is it able to pass the Great Firewall, are Chinese able to use Tor and how difficult it is for them to use Tor from china, how effective does the Chinese Gov get in blocking Tor now (in comparison with in the past)??

(I post the questions here since the Tor Browser 7.0.2 post isn't allowed comments).
