Peter：WangGang, I have something to ask you.
王刚：Of course, speak!
Peter：My company needs me to take a business trip to Shanghai, but I don’t know how to buy train tickets. I have never been on the trains in China before.
王刚：No problem, it’s simple. You can buy a ticket directly from the train station. Tell the ticket-seller where you are going, and what time you wish to go.
Peter：Is there a method for buying them online? In China, buying in this manner is very convenient.
王刚：Yes, you can download an app: 12306app. First register, then according to the prompts, you can enter the place and time you wish to travel. Super convenient!
Peter：Thanks, I’m off to try it.
