The 30-second answer
If your spreadsheet says "Beijing to Xi'an, 4.5 hours on the train, check," you have undercounted by roughly three hours. A travel day is not the train ride. It is check-out, transit to the station, security and waiting, the ride itself, transit to the next hotel, check-in, and the energy to do anything afterward. Most travelers feel the day as lost for sightseeing.
China rewards linear routes. The country is the size of Europe, so a loop that returns you to your start city burns a day you could spend at an attraction. The fix is simple to describe and hard to internalize: move less, and when you do move, move in one direction.

A 4.5-hour train between Beijing and Xi'an looks like a half-day slot. On the ground it runs closer to six or seven hours of your day:
| Step | Real time |
|---|---|
| Pack, check out, travel to station | 1 to 1.5 hrs |
| Station security, waiting, boarding | 0.5 to 1 hr |
| The train itself | 4.5 hrs (Beijing–Xi'an) |
| Arrive, transit to hotel, check in | 1 to 1.5 hrs |
| Settle, recover, plan the evening | 0.5 hr plus |
Train vs flight: the door-to-door math
Flights look faster on the schedule but lose on total time for short and medium routes. Chinese airports sit far from city centers, and you clear security plus immigration on arrival. Add it up:
| Route | Train door-to-door | Flight door-to-door | Winner |
|---|---|---|---|
| Beijing → Xi'an (4.5h rail) | ~6.5 hrs | ~7 hrs (2.5h flight + 4.5h overhead) | Train |
| Beijing → Shanghai (4.5h rail) | ~6.5 hrs | ~7 hrs | Train |
| Xi'an → Shanghai (6.5h rail) | ~8.5 hrs | ~8 hrs (rarely worth it) | Toss-up |
| Guilin → Beijing (~10h rail) | ~12 hrs | ~7 hrs | Flight |
| Chengdu → Guangzhou (~8h rail) | ~10 hrs | ~6.5 hrs | Flight |
Open-jaw tickets: skip the return leg
An open-jaw (multi-city) flight books you into one city and out of another. For China this is the single biggest route-efficiency win most first-timers miss.
Example: fly into Beijing, tour Beijing → Xi'an → Shanghai by train, then fly home from Shanghai. Without open-jaw, you would train back to Beijing first, spending a full extra day and a redundant hotel night just to return to your entry point.
Linear route beats the loop
How many buffer days to build in
A buffer day is a scheduled nothing. No trains, no must-see, no alarm. It absorbs delays, a bad weather day, or the simple need to sit down. Build them in on purpose, not as a panic response.
| Trip length | Buffer days | What they cover |
|---|---|---|
| 7 days | 0 to 1 | One rest half-day; keep the route tight |
| 10 days | 1 | Delay or a slow city morning |
| 14 days | 1 to 2 | Weather, a missed train, or spontaneity |
| 14+ with 5 cities | 2 | Recovery plus a flexible slot |
The real cost of a city change
Beyond the ticket, every move carries hidden cost: a hotel night you would not otherwise book, a meal grabbed at the station, and the sightseeing day you did not have. Rough per-move totals for an independent traveler:
| Move type | Ticket | Extra (hotel gap, food, transit) | Day cost |
|---|---|---|---|
| Train, < 6h, no hotel change | $30–95 | $20–40 | ~0.5 day + $50–135 |
| Train, with hotel swap | $30–95 | $70–150 | ~1 day + $100–245 |
| Domestic flight | $80–200 | $70–150 | ~1 day + $150–350 |
Transit mistakes that wreck a route
- Counting only rail time. A 4.5-hour train is a 7-hour day. Plan the day as gone.
- Looping back to the start. A round trip to your entry city burns a day. Fly open-jaw instead.
- Flying short hops. Under 6 hours of rail, the flight is slower door-to-door and lands you far out of town.
- Two moves in 48 hours. You get a zero-sightseeing stretch. Separate moves by at least two nights.
- No buffer before fixed bookings. A delayed train that misses a capped-attendance slot is money gone.
- Packing the travel day with sights. The long flight or train is the plan. Do not also schedule the Forbidden City.
FAQ
Is the train always better than flying in China? No. Under about 6 hours of rail time the train wins on total time and convenience. Above 8 to 10 hours, or on long diagonals, the flight saves a real half-day or more.
What is an open-jaw ticket and why use it? It flies you into one city and out of another, so you tour in a line and never return to your start. For China that typically means Beijing in, Shanghai out.
How many cities can I realistically do? Three in 10 days, four or five in 14 with buffer days. Each added city is a half to full travel day plus a hotel change.
Should I book trains or flights first? Lock the international open-jaw flight early for price, then book domestic trains 15 to 30 days ahead as they open. Flights between Chinese cities can wait until the route is fixed.
Where do buffer days help most? Right before any capped or non-refundable booking: the Li River cruise, the panda base, the Great Wall cable car on a peak day.

Your leg is a medium-distance city pair
Beijing–Xi'an, Beijing–Shanghai, Xi'an–Chengdu. Take the train. Central stations, table seats, and you arrive in the city, not 40 km out.
Your leg is a long haul or diagonal
Guilin–Beijing, Chengdu–Guangzhou, Kunming–Shanghai. Fly. The rail time crosses 10 hours and the plane saves a real day. Book as one open-jaw wherever possible.
