China generally requires a visa, but some travellers can use limited visa-free transit schemes (e.g., 72/144-hour transit) in certain cities when flying through on eligible itineraries. A Chinese businessman mentioned visa-free entry to several cities, but details were unclear, and others in the chat had no firm information. Always check the latest official Chinese embassy or consulate guidance for your nationality, especially if you plan to visit multiple cities rather than a single transit stop.
