When you get on the bus, you will find that the sleepers (hard sleepers) are all upper, middle and lower floors, and each group of sleepers has three floors. The aisle of each group is marked with the number of sleeper groups, as well as the upper berth, middle berth and lower berth. On the sleeper, each group is a serial number on the ticket, and the serial number is divided into upper, middle and lower berths. Go along the aisle in the carriage and find the corresponding position of the number in the carriage marked on the ticket. For example, 1 The lower berth of the first group of cars is under 1 cars. The unit level of train hard sleeper car is divided into car ~ sleeper group ~ sleeper number.
Sleeper refers to a sleeper for passengers to sleep on their back, which is essentially a small bed placed in long-distance transportation. Cars, trains, cruise ships and even airplanes can be equipped with sleeping berths.
There are two kinds of sleeper grades for passenger trains in China: soft sleeper and hard sleeper, among which soft sleeper is subdivided into advanced soft sleeper and ordinary soft sleeper. The sleeper of EMU trains is also referred to as moving sleeper, which is generally soft sleeper.
