You land, follow the signs for taxi, and see the queue: a snake of suitcases forty minutes long. Ten steps away, a row of fare gates swallows a thousand commuters without breaking rhythm. That gate is the best infrastructure deal in China: the metro is clean, air-conditioned, bilingual, and a typical ride costs less than a bottle of water. The word you need is 地铁 (dìtiě, literally “ground-iron,” the underground railway), and it is posted over entrances in every big city.
Beijing opened China’s first metro line in 1969; today more than 50 mainland cities run urban rail, Shanghai operates the largest metro network in the world, and Beijing’s is close behind. The design is friendlier to non-readers than almost any system you have used: lines are color-coded and numbered, station names repeat in characters and pinyin, and announcements switch to English. What the signage does not explain is how to pay, what happens at the security scanner, and why the direction sign on the platform names a station you have never heard of. Ten minutes on this page covers all three.
Three Ways Through the Gate
1. The transit QR code — the default for almost everyone
Set it up once, ride forever. In Alipay, open the 出行 (chūxíng, “travel”) tab, pick your city, and authorize the city’s transit code. From then on the app generates a fresh QR code for each ride, which you tap on the blue scanner panel at the gate. WeChat runs the same flow through its 乘车码 (chéngchēmǎ, “ride code”) mini program. The fare bills to your default payment method as you pass; the gate reads the code in about a second. If you have not set up payments yet, the WeChat Pay and Alipay guide walks through that part first.
Shanghai adds one more door for rail arrivals: the city’s integrated Suishenma (随申码) transport code can be activated through the 12306 platform when you arrive by train, and foreign users are eligible for the same discounts as residents, one of the few places where the visitor setup equals the local one.
2. Your own contactless bank card — Beijing led, others followed
Beijing’s fare gates accept foreign contactless bank cards directly. Visa and Mastercard went first in September 2024, and since June 15, 2025 all five major networks (UnionPay, Visa, Mastercard, JCB, and American Express) work across the whole network, including the S2 suburban line, according to the city’s foreign affairs office. Tap the card, or a phone wallet loaded with a supported card, exactly where a transit card goes, and you pay the same local fare as everyone else: no app, no registration, no Chinese phone number.
Shanghai, Guangzhou and Shenzhen have opened the same tap-to-ride gates since (Shanghai went network-wide on June 28, 2025), so a foreign contactless card now covers the biggest arrival cities. Treat it as a bonus, though, not a plan: smaller cities and older gates remain card-only for local banks, while the QR code works in essentially every city with a metro.
3. Ticket machines — no phone setup required
Every station has touch-screen machines with an English button. Pick your station from the map or list, the fare shows on screen, and you pay with coins, small cash, or by scanning the machine’s QR code with Alipay or WeChat. No passport, no registration. What drops out is a single-journey ticket, 单程票 (dānchéngpiào): in most cities a small round plastic token you tap at the entry gate. At the exit, some cities want the token dropped into a slot, others want it tapped again; the gate’s light and the person ahead of you will settle the question.
Fares and When a Day Pass Wins
Fares are distance-based and cheap. Shanghai charges ¥3 for the first 6 kilometers, then ¥1 for each additional 10; Beijing starts at ¥3 and climbs on a similar curve, so most sightseeing rides land between ¥3 and ¥6, roughly $0.40 to $0.85.
If you are riding hard, the passes are honest value. Shanghai’s One-Day Pass costs ¥18 and covers unlimited rides for 24 hours from first entry; the Three-Day Pass is ¥45 for 72 hours. Both are sold at any station ticket booth, and both exclude the Maglev (磁悬浮, cíxuánfú) and the newest suburban railway lines. The math is simple: at ¥3–6 a ride, the day pass breaks even around the fourth ride. Two rides a day? Pay per ride. On a museum-crawl day with four hops across town, the pass has paid for itself by lunch.
安检: The Security Line Before the Gate
Every entrance has one: bags through an X-ray, you through a metal detector, occasionally a request to sip from your water bottle to prove it is water. It looks airport-grade but moves like a turnstile, under a minute most hours. At rush hour, the line you are standing in is almost always the security line, not the ticket line, which is one more reason the QR setup matters: it takes the ticket machine out of your critical path.
Reading the Platform: Direction, Transfers, Exits
Lines are numbered (2号线, èr hào xiàn, “line 2”), and each line runs in two directions named for its terminal station: the sign reads 往 (wǎng, “towards”) plus the end-of-line name. Find your destination on the route map, note which terminus it falls under, and ignore everything else. For changes, follow the 换乘 (huànchéng, “transfer”) arrows; interchanges are signed from platform to platform, and in big cities every announcement repeats in English.
Exits get letters (A, B, C, D), and large interchanges can have a dozen or more. The exit letter decides which street corner you surface on, so check the small map beside the letters before you ascend; at stations like People’s Square in Shanghai, the wrong letter costs you a couple of city blocks.
Hours are predictable: most networks run from around 5:30 a.m. until around 11 p.m., and the 末班车 (mòbānchē, “last train”) time varies by line and direction. Out late? Check the app before you rely on it, and keep the taxi phrases handy as the fallback.
Crowds, Cars, and the Small Rules
Rush hour runs roughly 7:30–9:00 a.m. and 5:30–7:00 p.m.; at its worst you board shoulder-to-shoulder, but trains come every two to three minutes, so the crowd clears as fast as it forms. The rules that matter: stand behind the floor markings and let people off first; the priority seats (爱心专座, àixīn zhuānzuò, “caring seats”) are for elderly, pregnant, and disabled riders even when the car is packed; and eating or drinking in the carriages is prohibited in most cities. Phone signal holds up underground on the major networks, so your maps keep working in the tunnel. Luggage is allowed and completely normal; off-peak, the airport cars double as suitcase storage, and the main airports in Beijing and Shanghai are all rail-connected to town.
The Phrases That Matter
- 去地铁怎么走？ (Qù dìtiě zěnme zǒu?) — “How do I get to the metro?”
- 这是几号线？ (Zhè shì jǐ hào xiàn?) — “Which line is this?”
- 到不到南京东路？ (Dào bu dào Nánjīng Dōng Lù?) — “Does this train stop at East Nanjing Road?” Drop in any station name.
- 在哪儿换乘？ (Zài nǎr huànchéng?) — “Where do I transfer?”
- 末班车几点？ (Mòbānchē jǐ diǎn?) — “What time is the last train?”
- 最近的出口在哪儿？ (Zuìjìn de chūkǒu zài nǎr?) — “Where is the nearest exit?”
Why the Metro Becomes Your Default
The first day has three small novelties at once: the security scanner, the QR authorization, the direction-by-terminus logic. By the second day they are muscle memory, and the metro becomes the connective tissue of the trip: the rail-connected way to reach the train stations for the high-speed network (buying those tickets is its own guide), the way home from the airport without a fare negotiation, and the fastest two yuan you will ever spend crossing a city.
If you are staying longer than a trip (a lease, a job, a student card), your name is the next piece of setup: it needs to read consistently on transit cards, contracts, and campus forms. ChineseToolkit’s personal name checker helps you pick a Chinese name that holds up across all of them.
The taxi queue at the airport is the last long line you will stand in this trip. The city under the street runs on rails from here.
