leroy11: I would
very strongly advise you use the services of a specialist Visa Service, or ask your airline to sort out the visa for you.
The only other advice I can offer is to ensure you include an address local to your destination in China (preferably a hotel where you have a reservation) or your application will be automatically rejected.
You may like to take a look at this web site, which may have links which are of use to you:

Also you may like to try and obtain a copy of the leaflet
"The Little Red Book" produced by Virgin Atlantic for passengers on their Shanghai route (Ok, I confess I have flown Virgin on occassion

).
