Get a Business visa via a China handler arranging the invitation. The timeframe if ur efficient and they are is 2-4 days for that. Go to the consulate or embassy and expect 1-5 days handling, pay for express service. Expect invitation letter from China country cost approx 100usd and Express Visa service approx 100usd. Agree Business Visa much more
ussfull than screw visa. Good luck.
