What do you mean by a hard seat on a train ticket?

Hard seat is a kind of seat installed on passenger trains on China National Railway Line, which has the lowest comfort, but the cheapest fare. The name of hard seat is limited to non-EMU passenger trains. The seat cushion of the second-class seat of Harmony CRH6 EMU is not soft, which belongs to the hard seat in fact, but it is still called the second-class seat, and tickets are sold at the standard price of the second-class seat.

The hard seat of the early green leather car had no seat plate and elastic cushion, but was wrapped in simple leather, so the comfort was very poor. After a large number of old green leather cars were eliminated, the hard seats of red leather cars, blue leather cars, white leather cars and new green leather cars have been greatly improved, and the cushions are more comfortable than before. However, because the hard seat cannot adjust the seat, it will be uncomfortable after a long time, usually within four hours.
