What is the difference between first-class and second-class sleepers on the D703?

[VonCharlotte]

The differences between first-class and second-class sleepers on the D703 are as follows: 1. In terms of activity space: A first-class sleeper compartment has only four beds, while a second-class sleeper has six, so the average space per person is naturally larger in the first-class sleeper. Since there is no middle berth in first-class, people on both the upper and lower berths can sit up straight, whereas in second-class sleepers, only those on the lower berth can do so. 2. In terms of privacy: First-class sleeper compartments have doors, allowing occupants to close them at any time, preventing passersby in the corridor from seeing inside, making it more secure. Second-class sleeper compartments do not have doors, so passersby can see everything inside. 3. In terms of facilities: Ordinary first-class sleepers have four people per compartment, while deluxe first-class sleepers have two people per compartment, but not all trains have deluxe first-class sleepers. Deluxe first-class sleeper compartments come with a washroom, sofa, LCD TV, call phone, and other amenities. In 25K and 25T first-class sleeper cars, there are TVs, and disposable slippers and toiletries are provided.
