What to do next
A practical answer should leave the traveler with a few moves they can actually make before the trip or at the point of friction.
Save the school, dorm, or hotel address in Chinese and keep screenshots offline.
Prepare data, payment, messaging, maps, and translation before the flight, then test what can be tested.
Know who can help locally if the first transfer, SIM, wallet, or check-in step fails.
