Bus from Panyu to Guangzhou south railway station

It says above "How to get to the Station
1. By Bus: Buses Nos.225, 228, 238, 256, 290, 30, 34, 530, 543, 545, 7, Night15, Night18, Night45"
But it does not say where the buses come from. I want one from Nancun or Hanxi Changlong metro station. Shiqiao or Dashi metro station would suffice also, or Shiqiao bus station. I just need to know which number, thanks. Ken
