as of now, the Wechat accounts "activated" in China and the wechat accounts activated outside China have slightly different rules, to the point that you can have a 'non-chinese' account that create contents which can only be seen by 'non-chinese' accounts (and without any UI information about it).

Chinese accounts can also be 'semi-banned' where they will be able to read, but not to post video or audio anymore nor talk in groups.
