Is there any shuttle bus from cangzhou to beijing capital International Airport?

There should be 2 buses a day, based on the website of the airport. One should be around 8am and one at 2pm. The bus departs from Cangzhou West Coach Station. May take around 3.5 or 4 hours on the way without traffic problem. It would be better to ask the local people or the west coach station about the departure time again before departure.
