Entry scenario
A short Beijing stop can be a 240-hour transit candidate for a US passport only when China sits between two different countries or regions and the onward ticket, port, and stay area qualify.
Scenario input
Change any one of these details and the answer may change. This is why the page gives a boundary instead of pretending one passport rule fits everyone.
Result card
Use this as a decision filter, then let the official source make the final call before booking or traveling.
Direct answer
This can be a transit visa-free candidate, but only if the itinerary is a real international or regional transit route and the passenger has a confirmed onward ticket within the allowed stay.
Primary path: Check the arrival port, onward ticket, allowed stay area, and airline check-in interpretation before relying on the transit path.
Boundary
A US-China-US round trip is not the same as transit. The onward destination must be a different country or qualifying region.

Once the entry path is clear, the next risk is usually data, payment, airport transfer, tickets, or the first night.
Next move
Read enough to make the decision smaller, then open the checklist, search a specific question, choose a setup tool, or share the page with the person planning with you.
Use the checklist when the question has shifted from research to preparation.
Search by the actual problem: Alipay, eSIM, transit visa, first transfer, vegetarian food, or a city name.
Open recommendations when the task is clear enough for a short list to be useful.
