Comment (by amiableclarity2011):

 Today, in China, at first I can connect to Tor network through snowflake
 bridge. But after about 40 minutes or 50 minutes, I can't open any webpage
 in Tor browser. Currently, I can't connect to Tor network through
 snowflake bridge. It seems that China's firewall can automatically detect
 the snowflake proxies and automatically block the snowflake proxies that I
 use.

 Below are the Tor log messages.
