Comment (by amiableclarity2011):

 Hello, I delete the Tor browser folder and unzip the tar.xz file again. At
 first I can connect to Tor network through snowflake bridge. But after
 about 30 minutes I can't open any webpage in Tor browser. Currently, in
 China I can't connect to Tor netowrk through snowflake bridge. Maybe
 China's firewall can recognize the characteristic of the traffic which
 flows to snowflake proxies and automatically block the Snowflake proxies
 that I use.

 Below are Tor log messages.
