Mike, shall we book two tickets online?
Fine. Shanghai and Beijing are thousands of miles away. How about bullet train? Faster and relatively cheap, I think.
Yeah. How many tickets remain?
Oh, what a shame. Only sleeping cars have tickets. Others are all out of stock. The price of the sleeping car is almost the same as the airplane. You see, the discount plane tickets are no more than 500 yuan. A good deal, isn't it?
