Hi,
I will be spending a night in Pingyao and have decided to take the bullet train that depart from Taiyuan to Beijing the next day.
1) Can I buy the bullet train ticket at Pingyao train station when I reach there?
2) If not, do I need to buy in advance the bullet train ticket from Taiyuan to Beijing or can I just buy it at the Taiyuan station when I depart from Pingyao.

Thanks
