Hi i would like to know how much would a bus cost from jingzhou to guangzhou.

As I know, in Chudu Bus Station, there are two buses available, leaving at 09:00 and 07:40, the bus fare is CNY280, and the travel time is about 20 hours.
By the way, there are two bullet trains available, too. The bus leaves at 09:20 and 10:26, the travel time is about 6.5 hours, and the fare is CNY523 for the second class seat and CNY823 for the first class seat.
