If you are visiting S. China from Hong Kong you might consider the bus. Tickets for most forms of travel can be purchased from China Travel Service or other vendors and you can catch a multitude of flights, ferries, busses and trains to China on a daily basis.
Thinking of visiting Shanghai or other industrial areas like Cixi, Ningbo or Hangzhou from Hong Kong. Instead of paying extra to travel from Hong Kong, why not take a bus directly to/from Shenzhen airport to benefit from cheaper flights?
The duration will be around three and a half hours, including stopping at immigration but best to estimate longer than that. Worried that you may have to rush to check in your flight? Chinalink also offers check-in services for you as you await for the next bus to take you to Shenzhen from the TST branch.
