A little update on the 5 day visa: (I asked them today)
UK 304 (it's actually on the board)
FR - no visa!
Full China visa at the border - currently impossible!
But (in China there is always a 'but'), you can get a 'Group Visa' if you travel in a group of at least 2 people. Cost for most passports is RMB 330/person. Full China visa, valid 1 month. Condition: the group must entry and exit together.
