China’s train network is the world’s most extensive high-speed rail system combined with a vast conventional network — over 155,000 kilometres of track in total. The classification system for seats and sleepers is logical once you understand it, but confusing when you first encounter the Chinese abbreviations.
This guide explains every class on every major train type, with honest advice on when to spend more and when to save.

Train Types
Before seats, you need to understand the train types, indicated by the letter prefix on the train number:
G trains (高铁): High-speed, up to 350km/h. The newest and fastest. Only first and second class seats, plus a business class. All reserved seating. The premium product.
D trains (动车): High-speed, up to 250km/h. Older or lower-grade high-speed. Similar seat classes to G trains. Some D trains run overnight with sleeper cars.
C trains (城际): Intercity express, short-distance, high-speed. Similar to G/D seats.
Z trains (直达特快): Express overnight trains. Not high-speed. The premium overnight service with the best sleeper cars.
T trains (特快): Express trains. Older rolling stock, lower speeds. Popular for overnight journeys.
K trains (快速): Regular express. Budget overnight option.
L trains: Seasonal or extra trains during peak travel. Usually budget.
High-Speed Train Seat Classes (G/D/C Trains)
Business Class (商务座, Shāngwù zuò)
The most expensive option on high-speed trains. A 2-1 configuration (one seat on one side, two on the other). The seat reclines to nearly flat for sleeping on longer journeys. Wide armrests, plenty of space. Meals are sometimes included. Very clean.
Price: Roughly 3–4x the second class price
Worth it for: Very long journeys (5+ hours) if you value space and comfort
Example: Beijing to Guangzhou (8h), business class ¥2,700 vs second class ¥865
First Class (一等座, Yīděng zuò)
A 2-2 configuration. Larger seats than second class, slightly more recline. Quieter end of the carriage. No food service, but the seats are genuinely comfortable.
Price: Roughly 1.5x second class
Worth it for: Journeys over 3 hours where you want to work or sleep more comfortably
Second Class (二等座, Èrděng zuò)
The standard option. A 3-2 configuration (three seats on one side, two on the other). Seats are similar to a comfortable economy airline seat — upright, padded, with a tray table. Slightly cramped for very tall people.
Price: The benchmark. Most reasonable choice for most journeys.
Not worth it for: Very long journeys (6+ hours) if you’re trying to sleep properly
Note on the middle seat (C seat) in three-seat rows: If you book the aisle seat in a two-seat row (A/B side), you get more elbow room. If you’re with a partner, booking A and B gives you a pair without a stranger between you.
Conventional Train Classes (Z/T/K Trains)
These trains don’t have the same clean class hierarchy as high-speed trains. They’re slower but often significantly cheaper for medium-distance routes.
Soft Sleeper (软卧, Ruǎn wò)
Four-berth compartments with a door. Two berths on each side, stacked. The most private and comfortable option on overnight trains. Beds come with a pillow, sheet, and light blanket. The compartment can be closed. Outlets for charging (one per compartment).
Price: Higher than hard sleeper, significantly lower than an equivalent high-speed trip
Best for: Overnight journeys when you want genuine privacy and sleep
Upper vs lower bunk: Lower bunks are slightly wider and cost a small premium. Upper bunks are cheaper but require climbing and have less headroom. Middle is the compromise. Most foreigners prefer lower for ease; Chinese travellers often prefer upper for slightly more privacy from corridor traffic.
Hard Sleeper (硬卧, Yìng wò)
Open-bay sleeping — six berths in an open bay (three per side), no door. Less private than soft sleeper but perfectly comfortable for sleeping. The berths are padded platforms with a pillow and blanket. Despite the name, they’re not hard.
Price: Budget to mid-range
Best for: Budget overnight travel where you don’t need privacy. The open-bay culture means you’ll interact with your bay-mates — most Chinese travellers see this as entirely normal and many are friendly.
Berth selection (upper/middle/lower):
- Lower berth: Most expensive in the bay. More communal — other passengers often sit on the edge of your berth during the day. But easy to access and wider.
- Middle berth: Compromise. Quieter than lower after lights-out.
- Upper berth: Cheapest. Most privacy when lying down. Less headroom. Requires climbing up a small ladder.
Soft Seat (软座, Ruǎn zuò)
Padded, reclining seats in a 2-2 configuration. Found on some older trains and conventional trains. More comfortable than hard seat, less so than high-speed second class.
Hard Seat (硬座, Yìng zuò)
The budget option. Rigid, upright seats in 3-2 rows with no reclining. Entirely functional for short journeys (under 2 hours). For overnight or long journeys, hard seat is genuinely uncomfortable and not recommended unless the journey has no other option.
Price: Very cheap
Environment: Hard seat cars are the noisiest and most chaotic part of Chinese trains — also the most sociable if you’re open to it
Standing Ticket (无座, Wú zuò)
Technically a hard seat ticket without a guaranteed seat — you can board but must stand or sit in the corridor. Sold when seated tickets are sold out. Only practical for short trips. Not recommended for foreigners unless there’s genuinely no alternative.
Which Class to Choose: A Decision Guide
Short high-speed journey (under 2 hours): Second class. No need to spend more.
Medium high-speed journey (2–4 hours): Second class unless you’re working and need the table space (first class gives slightly more room).
Long high-speed journey (4+ hours): First class or business class if budget allows. The difference in comfort over 6+ hours is significant.
Overnight journey (8–14 hours): Hard sleeper is the best value. Soft sleeper if privacy matters. Avoid hard seat overnight.
Very long overnight (14+ hours): Z train soft sleeper or D train sleeper if available. The best rolling stock has proper beds and the journey passes more comfortably.
Booking Tips
- Book early: Popular routes and sleeper berths sell out weeks in advance, especially during Chinese holidays (Spring Festival, Golden Week)
- 12306.cn is the official booking platform. Has an English interface but can be temperamental with foreign credit cards. Use a third-party service (Trip.com, China DIY Travel) if you have payment issues.
- Lower berths on sleepers are often the first to sell out. Book immediately once your travel dates are confirmed.
- The food cart comes through periodically on most trains. Pre-packaged meals, instant noodles, snacks. Bring your own food if you’re particular.
- Charging: High-speed trains have outlets at most seats. Conventional trains have outlets in soft sleeper compartments; hard sleeper has limited shared outlets near the toilet.
