Sources, scope and uncertainty

Know what a detail is based on.

A useful fact belongs to a specific branch, ticket, channel and date range.

Real places, with their sources attached

The Shanghai directory now contains real branch profiles assembled from public sources. Each profile links to the pages behind its address, ticket references and reported rules, with reading dates and unresolved details. These are informational profiles: the merchants have not confirmed this collection, and we have not visited the branches.

A webpage check is one kind of evidence

Reading a public page, receiving a merchant’s answer and visiting in person are different activities. A reading date tells you when we checked the source, not when the merchant last updated it. It does not establish current opening, live capacity, foreign-guest admission or a reservation.

We match the branch name and address before using a source. If two sources disagree—or a page disagrees with itself—we show the conflict. We do not silently choose the more convenient version.

A reference price is not a quote

An official public tariff, a ticket-product page and an editorial amount have different limits. A tariff without an effective date is a reference. A product page without a selected ticket, visit date and full conditions is not a usable offer. Historical amounts and unavailable search-result offers are not current prices.

A complete estimate needs the applicable ticket and date, adult eligibility, permitted entry and stay, and every required charge. Missing service fees or overnight surcharges are not treated as zero. Reference amounts are not multiplied into a confident group total or used to claim a plan is within budget.

Unknown stays unknown

Missing prices do not mean free admission. Missing fees do not mean all-inclusive. A hotel’s guest policy does not establish bath-ticket admission, and a generic ID requirement does not confirm that a foreign passport is accepted.

Until the necessary details are confirmed, the real profiles keep those gaps visible and automatic quotes unavailable. A channel link lets you inspect the source or ask the provider; it does not make a booking or guarantee the same price.

Sources can change

Stale, conflicting or unavailable evidence needs another check before it can support a decision. Revisions should appear wherever the fact is used: lists, details, comparisons and newly created visit cards. A downloaded card remains a snapshot, so recheck before travel.

We do not present generated illustrations or unlicensed third-party photos as photographs of a real branch.
