China Travel Glossary

The terms that show up while planning a China trip — in visa policy pages, booking confirmations, train tickets — explained in plain English, without the jargon they're usually buried in.

Visas & entry

Unilateral visa-free entry
China lets citizens of certain countries enter without a visa, for up to 30 days, purely as a policy China set on its own — no reciprocal agreement required. This is the most common visa-free route for travelers from Europe, Australia, New Zealand, and several other regions. Check if your passport qualifies →
Mutual (bilateral) visa-free agreement
A visa-free arrangement negotiated between China and another specific country, where both sides' citizens can enter each other's country without a visa. Terms (days allowed, purposes covered) vary by agreement rather than following one standard rule.
240-hour transit (visa-free transit)
A rule letting travelers from eligible countries stay up to 240 hours (10 days) without a visa, as long as they're transiting to a third country or region and enter through one of the designated ports. It's not full visa-free entry — it only applies if you're passing through, not making China your final destination. Check 240-hour transit eligibility →
L visa
The standard Chinese tourist visa, applied for in advance at a consulate or embassy, for travelers who don't qualify for visa-free entry or need to stay longer than the visa-free allowance covers.
X1 / X2 visa
Student visas. X1 is for programs longer than 180 days (requires a temporary residence permit after arrival); X2 is for shorter programs, usually single-entry.
Exit-Entry Permit
A separate travel document (distinct from a passport or visa) that mainland Chinese residents use to visit Hong Kong, Macao, or Taiwan. Not something foreign tourists need — this term shows up in searches but doesn't apply to visitors entering mainland China.

Payments & money

Alipay
China's dominant mobile payment app, now accepting foreign credit and debit cards directly. Functions as the default "wallet" for nearly all in-person transactions — restaurants, taxis, metro gates, vending machines. Alipay setup guide →
WeChat Pay
The payment feature built into WeChat, China's messaging super-app. Works similarly to Alipay and is worth having as a backup, since a handful of merchants and QR menus are WeChat-only. WeChat Pay guide →
Real-name verification (payment apps)
The identity check Alipay and WeChat Pay require to unlock full spending limits — typically a passport scan and a linked card. Skipping it caps how much you can pay per transaction or per day.
UnionPay
China's dominant bank card network (like Visa or Mastercard elsewhere). Some ATMs and card terminals accept UnionPay more reliably than foreign Visa/Mastercard, though this matters far less than it used to now that Alipay and WeChat Pay both take foreign cards directly.

Trains & transport

G-train
China's fastest high-speed rail service, commonly running 300-350 km/h. The letter prefix on a train number (G, D, K, T, Z) tells you the service tier before you even check the schedule. China train tickets guide →
D-train
A high-speed service slower than G-trains (typically 200-250 km/h), often cheaper and making more stops.
K-train / T-train
Older, slower conventional rail services (not high-speed), sometimes running overnight with sleeper compartments. Increasingly rare on popular tourist routes as high-speed rail expands, but still common for smaller cities and longer overnight hauls.
Hard seat / soft seat / hard sleeper / soft sleeper
China's train class names — "hard" and "soft" describe seat/berth comfort tiers, not literal hardness. Hard sleeper (a 6-berth open compartment) is the budget-traveler favorite for overnight trips; soft sleeper (a 4-berth closed compartment) costs more for more privacy.
Real-name ticketing
China's system tying every train ticket to the passport (or ID) used to book it. You board by scanning that same passport at the gate — there's no paper ticket to lose, but you also can't transfer a ticket to someone else.
12306
China Railway's official ticket-booking platform (app and website). Zero booking fees and first access to inventory, but more setup friction for foreign travelers than third-party platforms like Trip.com. 12306 vs. Trip.com →

Accommodation & registration

Foreign guest registration
A legal requirement for anyone staying in China to register their presence with local police within 24 hours of arrival. Hotels handle this automatically at check-in by scanning your passport — it's the reason check-in requires the physical document, not a photo of it. Hotel booking guide for foreigners →
PSB (Public Security Bureau)
China's local police administration, the authority responsible for foreign-guest registration and visa-related paperwork. Travelers staying with friends or in a private rental (rather than a hotel) need to register with the local PSB themselves within 24 hours.

General & culture

Golden Week
Two major annual holiday periods — around May 1st (Labour Day) and October 1st (National Day) — when domestic Chinese travel surges and popular sites get significantly more crowded. Worth planning around rather than into, if flexible. Full crowd calendar →
Chunyun
The Spring Festival travel rush around Chinese New Year — the largest annual human migration in the world, as people travel home for the holiday. Trains and flights sell out fast and prices spike; most foreign tourists plan trips outside this window entirely.
Hukou
China's household registration system, which ties a citizen's public services (schooling, healthcare access) to a specific city or region. It's a major topic in Chinese domestic policy but doesn't affect foreign tourists directly — it shows up in searches mostly because it's widely discussed in China-focused reading.
Tier 1 / Tier 2 / Tier 3 city
An informal but widely used way of ranking Chinese cities by size, economic weight, and infrastructure. Tier 1 (Beijing, Shanghai, Guangzhou, Shenzhen) means the most English signage, the most developed metro systems, and the easiest first-time-visitor experience; lower tiers mean more character but less English support.
Putonghua
Standard Mandarin Chinese, the official spoken language taught nationwide — as distinct from regional dialects (Cantonese, Shanghainese, and others) that remain common in daily life in their respective regions. What most translation apps and phrasebooks are built around.

Frequently asked questions

What's the difference between unilateral and mutual visa-free entry?
Unilateral is a policy China set on its own for specific countries — no agreement needed on the other side. Mutual is a negotiated agreement where both countries' citizens get visa-free access to each other. The practical difference for travelers is small (both usually mean 30 visa-free days), but it explains why the exact list of eligible countries and terms can look inconsistent if you're reading about it from different sources.
Is 240-hour transit the same as a 10-day visa-free visit?
No — it only applies if you're passing through China on the way to a third country or region, entering through a designated port, with proof of onward travel. If China is your actual destination, you need either unilateral/mutual visa-free eligibility or a standard visa.
Do I need to know these terms before my trip?
Not all of them — most travelers only ever need visa-free entry, Alipay, and G-trains. This glossary exists for the moment you hit an unfamiliar term in a booking confirmation, a visa policy page, or a train ticket, and want a fast, accurate answer instead of guessing.
