目前Tor被GFW封锁，但只要运用Tor的网桥功能就能成功突破GFW。

我试过了，非常好用，速度也很快。

Tor partially blocked in China

On September 25, 2009, the Great Firewall of China blocked the public list of relays and directory authorities by simple IP address blocks. Currently, about 80% of the public relays are blocked by IP address and TCP port combination. Tor users are still connecting to the network through bridges. At the simplest level, bridges are non-public relays that don't exit traffic, but instead send it on to the rest of the Tor network.

If you want to help people in China get access to the uncensored Internet, run a bridge.

Tor中继的公共目录被屏蔽。 80%的Tor公开目录中继被以IP地址和TCP端口组合的方式封杀。但Tor开发者早就预料到这一天会到来，他们开发出了应对措施，这就是Tor网桥，网桥中继是不被列在Tor主目录中的Tor中继，即使ISP屏蔽了所有已知Tor中继，也不可能屏蔽所有的网桥。Tor项目呼吁志愿者运行网桥，帮助被屏蔽的用户。
