Can I buy a train ticket for the first half and a sleeper for the second half?

You can make up the ticket later,

Buy two tickets before and after.

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.

Hard sleeper is a kind of ticket for China passenger train. It's affordable, but it's a little more expensive than a hard seat and cheaper than a soft sleeper. Passengers on overnight and long-distance passenger trains generally buy tickets. Hard sleeper is a sleeper bus facility for railway passenger cars in China.

Different from hard-seat cars and soft-seat cars in all aspects, the train ride mode is sleeper. When riding, passengers can lie down or sit. Compared with ordinary passenger cars, hard-seat cars are more comfortable and quiet.
