240h transit planning hub

Build the trip around a legal 240h route first

Start with entry port, mainland exit port, third-country or third-region destination, eligible stay areas, and the proof airline check-in will ask for. The sightseeing calendar comes after the route shape is legal.

The planning order

Do these in order before flights, hotels, or high-speed rail tickets become expensive to change.

Route

Choose a legal 240h route before booking flights, hotels, or trains.

Confirm passport eligibility, A to China to B country or region logic, mainland entry and exit ports, and the stay window.

Open Check

Hotel

Lock the first-night address with arrival-card proof in mind.

Use a foreign-passport-friendly hotel and keep the Chinese address consistent across CDAC, airline, and backup documents.

Prepare arrival card

Train

Book HSR only after the route is legal.

Handle passport name order, 12306 verification, payment, station entry, and exit-port proof after the transit route passes.

Core risk

The risky part is not whether Beijing or Shanghai is worth visiting

The risky part is whether your A to China to B route, exit mode, and stay areas survive airline check-in and Chinese border inspection. Treat the itinerary as a compliance problem first and a sightseeing plan second.

Route templates

Template routes that pass facts into Check

Each row uses a 240h port from the project policy snapshot and links directly to Check with the route facts pre-filled.

Route template	A to China to B example	Compliance watchpoint	Check route
Different mainland entry and exit ports Beijing in, Shanghai out to a third region Stay-area note: Beijing-Tianjin-Hebei plus Shanghai-Jiangsu-Zhejiang need linked-region attention.	SFO -> PEK -> PVG -> ICN	The onward destination after mainland China must be a third country or third region, not the same country or region as the origin before China.	Check route
Same mainland port, different onward region Shanghai in and out when A and B differ Stay-area note: Stay inside the Shanghai-Jiangsu-Zhejiang linked region covered by the snapshot ports.	SFO -> PVG -> PVG -> ICN	Using the same port is not the issue; origin and destination still need to be different countries or regions under the A to China to B rule.	Check route
Rail exit to Hong Kong Guangzhou or Shenzhen area with West Kowloon rail exit Stay-area note: Keep this as a Guangdong linked-region plan and carry the rail exit proof.	LAX -> CAN -> WEST-KOWLOON-RAIL -> HKG	WEST-KOWLOON-RAIL is in the current port snapshot, but airline staff may still ask for clear onward proof to Hong Kong as the third region.	Check route
Western China air exit Chengdu in, Chongqing out to a third country Stay-area note: Use Chengdu and Chongqing city guide facts, and re-check if adding other Sichuan stops.	HKG -> TFU -> CKG -> SIN	Sichuan and Chongqing are separate stay-area facts in the snapshot, so do not assume a whole western-China roaming zone beyond the listed plan.	Check route
Northern history route Beijing in, Xi'an out to a third region Stay-area note: Beijing is linked to Tianjin-Hebei in the snapshot; Xi'an is a Shaanxi port.	SFO -> PEK -> XIY -> ICN	The origin and destination still need to be different, and any extra northern stops need stay-area review before booking.	Check route
Guangxi scenic route Guilin entry with a third-region onward flight Stay-area note: Use the Guilin city guide and avoid assuming every Guangxi side trip is covered without re-checking the port and stay-area facts.	BKK -> KWL -> KWL -> HKG	Same-port Guangxi plans still need a different destination region after mainland China and confirmed onward proof at check-in.	Check route
