How we research

Our editorial methodology — on-the-ground verification, source standards, and update cadence.

• Our editorial policy
  How we choose what to write, who writes it, how often it is re-verified, and how AI is and is not used.
• Fact-checking policy
  Our source hierarchy, how claims are dated, and what happens when we get something wrong.
• Editorial corrections
  Every substantive correction we have made, what changed, and when — because China travel rules move.
• Affiliate disclosure
  Which links earn commission, which do not, and how placements are kept out of editorial decisions.

The method in one paragraph: we buy the tickets, link the cards and ride the trains ourselves; we photograph what we cite; time-sensitive rules are re-verified every quarter; and every page names the author responsible for it. These pages document the standards, the correction process, and how affiliate placements are kept out of editorial decisions.
