The main differences between first-class rooms and second-class rooms include space, privacy, facilities and price. The first-class bedroom provides more space, more privacy and better facilities, but the fare is correspondingly higher; Although the second-class sleeper is slightly inferior in these aspects, it is more cost-effective and more suitable for those passengers who care about the price.

The first-class sleeper is an advanced seat type on the train, which considers comfort and privacy more. This kind of seat usually has more space so that passengers can stretch as much as possible. Each seat is equipped with convenient charging sockets, reading lamps and storage facilities to meet the various needs of passengers when they travel.

In addition, the first-class bedroom is also equipped with independent partitions or curtains, which increases the privacy of passengers. It is worth noting that the ticket price of the first-class sleeper is correspondingly higher, but in order to provide a better ride experience.

The comfort of the second-class bedroom is slightly lower than that of the first-class bedroom, but it pays more attention to cost performance. The seat spacing in the second-class bedroom is usually smaller than that in the first-class bedroom, but it is still enough to accommodate passengers and make them feel comfortable. These seats are equipped with basic facilities, such as charging sockets and reading lights, but may not provide additional storage facilities.

In addition, there is no independent partition or curtain in the second-class bedroom, so there is relatively little privacy between passengers. However, the second-class sleeper is cheaper than the first-class sleeper, so it is more popular with price-sensitive travelers.
