How to get the bus station for buses to Kaiping from Guangzhou South Train Station?

Dear Chin. Walk northwards from the train station for about 350yd to the South Bus Station, where there are many buses to Kaiping directly. The schedules are 8:55-20:50 every an hour. It takes about 2.5h and costs CNY70/person. You will get to Kaiping Bus Station.
