Large cities have clear metro systems — use a transport card or mobile QR ticket linked to Alipay or WeChat. Follow the English + Chinese station names on maps.
For intercity travel, book high-speed trains via the official 12306 app or with campus help; bring your passport to board. Didi is the main ride-hailing option when you have luggage or late arrivals.
Start with short trips near campus until you feel comfortable with addresses in Chinese. Screenshot the destination name for the driver.
