@Wilhelm. Perhaps the best thing you can do is drive over to one, and ask directly at the clubhouse reception desk.
There are several golf course developments (mixed residential and golf course) in and around Kunming. Some were never got beyond planning, most were never commercially viable. We looked at buying a house in one of these developments about 10 years ago. The houses were around market value and each came with only one membership. Most people sold the memberships to third parties, and these were selling for 400k rmb. Additional memberships could not be bought from the developer. There were green fees that at that time were about 1000 rmb, and this was for a fairly basic golf course.
Golf in China seems to be largely an expensive membership sport.
Will they allow you to ship a frame?
I would not ask them, I would just strip the bike (incl. remove forks), wrap the frame and take it down to the post office. If they say they don't ship bikes, tell them it is not a bike, it is spare parts. See what happens.
If that works then the following week ship the wheels, etc.
If the cost of shipping is more than a component, e.g. bars, buy new bars back in the UK.
Maybe worth a try.
@AlPage. Have you tried using Mozilla Firefox to access your online banking?
I know that Google Chrome has created problems for me in the past as I cannot make online payments with my China Merchants Bank account using Chrome, but I am fine with Firefox. I am assuming it bay be the same with Chrome and other banks.
