阅读理解What is the most convenient (方便的) way to travel around China? By train, of course. There are some ways to buy train tickets. You can buy tickets at a train station or a train office, and you can also book online with a travel app, or at China Railway's official website. You can even book by your telephone.
Though most ticket windows at the train station serve 24 hours every day, the trouble is that you may stand in long lines. So make sure you arrive at the station at least one hour before the train leaves. And what is the easiest way to buy a ticket? Using your phone! It's simple to add the common user information in 12306 and fill in the full name following your passport. After finishing this step, 12306 will show that you have successfully registered (注册) and then you can book your tickets.
