Tor and bridges are effectively blocked in China, Russia, Turkmenistan, Belarus, and many countries in Asia. In any case, you will either have to run the latest snowflake versions from GitHub/GitLab yourself, or use most up-to-date firewall/DPI bypass tools, because Patrick and his team do not live in such countries, and governments quickly adapt to bypass methods. Follow bypass tools in thematic chats and forums + in GitHub topic (but use the tools at your own risk). For example, I found several scripts on GitHub to launch webtunnel bridges (these bridges are faster and more effective than snowflake).
