Guangzhou South to Yangshuo

I will be travelling from Guangzhou to Yangshuo via Guilin and I thought that I would have to take the rail to the GL North Station and then make my way to the GL South Station to get a bus onward to Yangshuo. When looking at booking my ticket on Ctrip at 1pm, there are two options, one to the North Station and one to GL (which seems to be about 20 mins away). If I stayed onto GL, would that actually be the South Station? Thanks!
