1. Hard sleeper cars: usually allocated in numerical order, that is, the lower berth of 0 1 and the upper berth of 02 are in one car, the middle berth of 02 and the lower berth of 02 are in one car, and so on.
2. Soft sleeper car: numbers are usually assigned according to the cars in the car, and numbers are assigned in alphabetical order in each car. For example, Shop 0 1 in Car A and Shop 02 are in a partition, and so on.
Whether the No.05 middle shop and No.06 middle shop of the 10 car you mentioned are in the same division needs to be determined according to the specific trains and stations. Generally speaking, the berth numbers in the same district are adjacent, but not all trains and stations follow this rule. Therefore, when purchasing tickets, you can ask the conductor or platform staff about the berth number allocation of the train.
