What does it mean when a soft seat becomes a hard seat and when a hard seat becomes a socket?

1: It’s a joke: One day I was sitting on the bus, and a girl (who I knew) just got on the bus. I patted my thigh and said to her: “Come here, here. There is a soft seat." Unexpectedly, the girl shouted: "Forget it, the soft seat will become a hard seat, and the hard seat will become a socket, and then you can't even walk."

2: "The soft seat will become a hard seat. "Hard seats, hard seats become sockets" refers to the fact that the treatment is getting worse and the situation is getting worse. Soft seats are comfortable to sit on, hard seats are not so comfortable, but you can still sit on them. The "socket" can only stand there like a plug inserted into the hole of the socket, unable to move.

3: Soft seat tickets, hard seat tickets, standing tickets.

1: Hard seat. Also known as hard board, it is a kind of train seat, divided into 3-seater and 2-seater. It is tolerable for short distances, but very uncomfortable for long distances, especially the green train. The hard seats have five seats in each row, separated by an aisle, with two benches on one side and three benches on the other, with less padding in the seat cushions and backrests. ?

2: Soft seat. There are soft seats, one with armrests and the other without armrests, which are more comfortable than hard seats. You have to sit in a designated seat. Not all passenger trains have soft seats, and the ticket price is more expensive than hard seats. The carriages are controlled and passengers without soft seat tickets cannot enter. Soft seats are currently divided into first-class soft seats and second-class soft seats. First-class soft seats have three seats in each row, and the seats are more comfortable. There are single seats on one side of the aisle and double seats on the other side. There is a glass door separating the aisle from the aisle, which is quite comfortable. Compared with the private box; the second-class (ordinary) soft seats have four seats in each row, two on each side of the aisle, which are wider. The seat cushion and backrest are independent, the padding is thick and thick, the comfort is better, and the chair back can be adjusted. ?

3: Hard sleep. There are bedding, and passengers can lie down on the berths to rest. They are divided into upper, middle and lower berths, and the price difference is not very big. Passengers without sleeper tickets cannot enter casually. ?

4: Soft sleeper. It is more expensive than a hard sleeper, but the facilities are comfortable. There are 4 people in a box, with upper and lower berths. Hot water bottles are provided. The environment is quiet and there is no disturbance. It is the most comfortable form of passenger train.
