I completely forgot that this thread existed. TBH, during the past 3 years, in addition to activity being sparse in this forum, the ~10 posters who have stayed the course are all up to speed on the basics.

But, you do raise a good point. Since people will presumably start to travel to China again fairly soon, an update is probably in order.

As I look over the Wikipost at the top of this thread, I think the topic list is okay (maybe add Wechat/Aliplay), but some of the redirect targets could be changed (e.g. the visa index item points to an old thread).
