Entry scenario
A 35-day Shanghai stay is outside the 30-day UK ordinary-passport visa-free window described by the current notice, so the traveler should check the correct visa or stay-permit path.
Scenario input
Change any one of these details and the answer may change. This is why the page gives a boundary instead of pretending one passport rule fits everyone.
Result card
Use this as a decision filter, then let the official source make the final call before booking or traveling.
Direct answer
Do not treat a 35-day Shanghai stay as covered by the 30-day visa-free policy. Start from the visa or stay-extension question before booking the full stay.
Primary path: Use the visa-free notice only as a boundary check, then confirm the correct visa category with the official visa center or embassy source.
Boundary
This is exactly where a short-stay policy can mislead travelers: the passport may be eligible, but the stay length is not.

Once the entry path is clear, the next risk is usually data, payment, airport transfer, tickets, or the first night.
Next move
Read enough to make the decision smaller, then open the checklist, search a specific question, choose a setup tool, or share the page with the person planning with you.
Use the checklist when the question has shifted from research to preparation.
Search by the actual problem: Alipay, eSIM, transit visa, first transfer, vegetarian food, or a city name.
