People prefer to buy tickets at these booking offices rather than go to the railway station . Because they think booking offices are easy to access and save much time for them even they will be charged extra 5RMB for handling fee.
So next time, you probably have a try to buy your own ticket at booking offices. But please don’t expect counter staff speaking English or your mother tongue to you. The smart or smooth way is to write down where you will go to and from, when, and train No. in Chinese if you could.
