How can I use Tor in China where network was blocked

I’m using the latest version of Browser, which was 11.0.4 (based on Mozilla Firefox 91.5.0esr). And after I install it, I haven’t been able to connect, either with the built-in Bridge or the Bridge I downloaded from Bridge DB. By the way, I was Recently in China.

Users in China need to take a few steps to circumvent the Great Firewall and connect to the Tor network.

Latest iteration of Tor Browser is 11.0.11
First, get an updated version of Tor Browser: send an email to gettor@torproject.org with the subject “windows zh-cn” or other operating system (linux or osx).

After installing Tor Browser, you will probably not be able to connect directly to the Tor network, because the Great Firewall is blocking Tor. Therefore, the second step will be to obtain a bridge that works in China.

There are three options to unblock Tor in China:

  1. Snowflake: uses ephemeral proxies to connect to the Tor network. It’s available in Tor Browser. You can select Snowflake from Tor Browser’s built-in bridge dropdown.
  2. Private and unlisted obfs4 bridges: contact our Telegram Bot @GetBridgesBot and type /bridges . Or send an email to frontdesk@torproject.org with the phrase “private bridge” in the subject of the email. If you are tech-savvy, you can run your own obfs4 bridge from outside China. Remember that bridges distributed by BridgeDB, and built-in obfs4 bridges bundled in Tor Browser most likely won’t work.
  3. meek-azure: makes it look like you are browsing a Microsoft website instead of using Tor. However, because it has a bandwidth limitation, this option will be quite slow. You can select meek-azure from Tor Browser’s built-in bridges dropdown.

By the way, you Were recently in China :thinking :thinking:
If Tor Browser doesn’t connect, there may be a simple solution. Try each of the following: Your computer’s system clock must be adjusted correctly or Tor will not be able to connect. If Tor Browser used to work and no longer works now, your system may have been in hibernation. Restarting your system will fix the problem. Remove Tor Browser and reinstall it. If you’re updating, don’t just replace your previous Tor Browser files; make sure beforehand that they are completely removed. :thinking:
