hi im here in champi dungguan,i just want to know where is the bus station from dungguan to Shanghai, how much is the fare?

Are you referring to Changping, Dongguan? If so, I remember there is a direct long-distance bus with sleepers at Dongguan Bus Station to your destination and it leaves at 13:00, but not sure about the fare. But there is around 1,500km between the two places, so the trip will be sufferring! I suggest you consider going to Guangzhou and then fly there!
