240h route assumptions
- Example origin airports: SFO, LHR, YYZ, SYD
- Mainland entry / exit: PEK → XIY
- First stop after mainland China: ICN
- Planned stay areas: Beijing, Shanxi, Shaanxi
Why this route shape works: Northern route with different mainland exit: Beijing in, Xi'an out, onward to a third country/region.
Watchpoint: Shanxi is city-limited under the official stay-area table. Keep the Shanxi stop to Datong or Taiyuan; do not swap in Pingyao unless the official table changes.
