What is the luggage weight limit for airplanes and high-speed trains?
Airplane (Domestic Flights): In economy class, checked baggage is mostly 20 kg per person (budget airlines require separate purchase), carry-on 5 kg, dimensions not exceeding 20×40×55 cm; single liquid container no more than 100ml, total up to 1000ml; lithium batteries and power banks can only be carried on, not checked in, and must be clearly labeled. High-Speed Rail: Adults 20 kg, children 10 kg, sum of length, width, and height not exceeding 160 cm (rod-shaped items 130 cm); no 100ml liquid restriction, but flammable items and controlled knives are prohibited.

Practical tip: for long-distance travel within China, you can send unused luggage to the next hotel by courier (SF Express across provinces takes 1–2 days, 20 kg costs about 60–120 RMB), traveling light yourself—this is a common local practice.
