A second-class: carriage has five chairs in a row - two on one side of the aisle and three on the other. They are not as large as first-class, with a width of 42cm, but the arms between two seats can be folded up.
The leg room is also smaller, about 40cm between two rows. The space is just like economy-class on airplane. The seat can turn 360 degrees. There is a foldable tray table attached to the adjustable backrest.
These seats are the most affordable on China's high-speed trains. Power outlets are provided. While not as spacious as other seats, second class seats are still a good option for passengers wanting a convenient journey.
Power for a laptop or mobile phone is available at the bottom of the seats by aisle. It is the cheapest class on the high speed trains.
The five chairs in a row are numbered A, B, C, D and F. A, B and C are on the three-seat side with A by the window and C by the aisle; D and F are on the two-seat side with D by the aisle and F by the window. Including the row number, a seat number can be , for example, 5D, 8B, or 9A.
Second class has two seats, an aisle and then three seats that are pretty close together. This section was completely full on both of our trains as it is less expensive than first or business class.
