The seat is bigger, the carriage is separate, there is a separate service staff, a pack of snacks, a bottle of drinks and a set meal are provided free of charge, and there is a public TV, which is hung on the carriage for everyone to watch and cannot be adjusted. Apart from sitting comfortably, it's not like there are drinks and food on the plane at any time.

each bullet train has only 16 special seats, with 8 seats at each end of the bullet train, which is the closest to the cab of the high-speed rail driver. Because the space is relatively independent and quieter, there are 3 people in a row, so it is equivalent to the first class in a passenger plane. The special seat area is also called the sightseeing area. Just press the button, the water mist on the glass can disappear instantly and become transparent. You can clearly see the scene in the cab and the scenery in front of the high-speed train. Just like driving, there is a gap next to the seat. Pull the handle inside, and you can see a desk lamp, which is convenient for reading. Some carriages are equipped with televisions and seat rotation systems to provide convenient services for passengers.
