Visa rules can change, so travelers should always confirm requirements with the Chinese embassy or consulate that serves their passport jurisdiction before departure.
Most guests should make sure their passport has sufficient validity, keep printed hotel and tour confirmations, and carry onward transport details.
If a transit visa policy may apply, verify the exact airport, eligible nationality, and permitted travel area before relying on it.
Note
Travel rules and transport conditions can change. Always verify official entry requirements and time-sensitive logistics before booking flights.
