I am a long term resident Here so yes I speak the language. For the flights I would book on Monday or Tuesday when there is always many free seats ,I make sure I am the last to get on so I can see where the empty rows are and I sit there and bed myself a 3-4 seater bed seat. This trick Really helps with PEM. Hotel prices are very good I recommend Genting Star at hong Kou area about 25 pound per night ,or motel 168 or the Jinjiang inn chain,all similar prices. I would consult Doctor Chen in advance (PM me for his email) he was the person that made my treatment plan despite the fact I got it done in another hospital,he is well known in asia and most will follow and adhere to his advice. If you want to book a private prioritized consultation with him since he is very busy you may have to ask for his private outcall rates as they most likely will be higher but nowhere near as pricey as the US.His English is fantastic.You should have prior evidence of a CFS ME or post Lyme diagnosis or other auto immune evidence to make things easier although without those it should still be possible just would be more slow and more evaluation would be made.
