China
Arriving
Every big city puts a rail line under its airport — the question is which one you want.
How do I get from the airport into the city?
Rail, in every case. Each major airport has a dedicated line, and the ordinary metro is always the cheap way in.
Does it matter which Beijing airport I land at?
Yes. Capital sits inside the city in Chaoyang; Daxing is far to the south with its own separate railway. They are not interchangeable.
Where can I leave my luggage for the day?
Metro station lockers. Shanghai runs them at 32 stations, sized by suitcase inches and charged by the hour with a daily cap.
Can I send my luggage ahead instead of carrying it?
Yes, but through the railway rather than the hotel. China Railway runs a luggage service at 19 stations, booked in the 12306 app.
Can I take a large suitcase on the high-speed train?
Within limits, free: 20kg per adult, and on high-speed trains each item's three dimensions may total no more than 130cm.
