China knowledge graph

City guides with attractions, transport, costs and itineraries for the places foreign visitors actually travel to. Start with the major hubs, then branch out by region.

Day-by-day plans from 3 to 21 days, each costed, mapped, and matched to a visa window.

Interactive helpers — trip cost calculator, Great Wall section picker, Alipay setup wizard, real trip budgets.

Side-by-side data on the choices travellers actually weigh — booking platforms, transport passes, payment apps — with a clear verdict.

The either/or questions: Beijing or Shanghai, visa-free or transit, hostel or hotel — each with a scoring table and a recommendation.

Symptom → cause → fix pages for things that actually break: Alipay declines, lost passports, blocked VPNs, 12306 card failures.

All 34 province-level divisions: what each is known for, its best season, key cities, and UNESCO sites.

Whether Visa, Mastercard, Amex, JCB, UnionPay and the rest actually work in China — and what to do when they do not.

Which passports get visa-free entry to China, for how long, and what the conditions are — country by country.
