I'm sorry for this to happen to you. Hopefully you will fully recover and this will go to your experience account without sequels.
Whenever we hear of someone who had an accident we instinctively compare notes. I don't wear a helmet, carry an adjustable spanner or a file. OTOH I never rush downhill and... aero bars,
really! 
Lessons for myself: quit being such a weight weenie and install that drag brake NOW!
May I ask which tires you had? How bad was the road so you
had to under inflate them to climb (photos?).
Heal, enjoy the rest of your trip: China is such an incredible country!
Best.
