METHODOLOGY · TRUST INFRASTRUCTURE

How We Verify

Every number on this site traces back to an official Chinese-language source, read in the original by people living in China. When the official text is ambiguous, we say so. When it changes, the change history stays.

PRINCIPLES · 三条铁律

Three Rules

  1. 1. Primary sources, in the original Chinese

    We read the NIA announcement itself — not a translated retelling of it. Every data page quotes the original text alongside our own English translation, with a direct link so you can check it yourself.

  2. 2. Ambiguity is flagged, never smoothed over

    Where official wording leaves room for interpretation (and it does), the page carries an amber note stating what is unclear, our reading, and what we recommend you do about it. A data page without an ambiguity section is a data page that isn't trying hard enough.

  3. 3. Change history is permanent

    When a policy changes, we update the data and log the change — old values are archived, never silently rewritten. You can see what was true last month, and when it stopped being true.

BADGES · 核实徽章说明

Reading the Badges

Verified at source

Checked against the primary official document within the page's re-verification cycle (7 days for visa policy, 14–30 days for practical guides).

Verified via official retelling

The primary document isn't public (e.g. platform help pages); we verified against the platform's own official channel, dated.

Pending verification

Publicly reported but not yet checked against the primary source. Treated as provisional — never presented as confirmed.

CORRECTIONS · 更正政策

When We Get It Wrong

Errors are corrected publicly within 48 hours of confirmation, and the correction itself is logged in the page's change history — including who pointed it out. A corrected number with a visible correction record is worth more than a number that was never questioned. Found something? [email protected]

AFFILIATE · 商业披露

Commercial Links Disclosure

Some pages carry sponsored links (insurance, eSIM, booking). Data pages stay neutral — conclusions are never shaped by commercial relationships, and every affiliate link is labelled sponsored. If a product we tested is worse than its commission suggests, that is what we write.
