No sign-ups, no paywalls. Instant utilities built to solve the four biggest friction points of independent China travel: mobile connectivity & GFW firewall bypass, visa-free transit flight rules, language barriers in taxis, and suburban day-trip transport math.
Configure your trip duration and phone OS to match the best firewall-free roaming eSIM (zero external VPN needed for Instagram/WhatsApp), complete your 6-app digital preparation checklist (Alipay, WeChat, Amap, Trip.com), and print an offline A4 emergency pocket wallet card.
Check if your passport qualifies for 30-day visa-free entry or 240-hour TWOV, validate your Country A → China → Region C flight tickets, and compute your exact midnight-adjusted departure deadline.
Filter airport terminals, Great Wall gates, Wulong Karst, rooftop bars, and peanut-allergy cards—or generate a custom full-screen hotel address card on the spot.
Slide your traveler count (1–8 pax) and luggage load to see exact per-person USD costs and door-to-door hours across China’s top suburban day excursions.
Calculate travel times, compare Second/First/Business class pods on Fuxing Hao trains, check Chinese station taxi cards, and reserve foreign passport e-tickets.
Generate a bilingual legal assistance card for front-desk clerks to avoid late-night foreigner check-in refusals, and access 100% verified hotels.
Calculate your power bank’s Watt-hours (Wh), inspect CCC certification rules, and avoid confiscations of sprays, knives, and self-heating meals at Chinese checkpoints.
