- Currency
- The Chinese yuan (renminbi, CNY). Cash isn't accepted everywhere, so the main way to pay is mobile wallets, and it is wise to carry some cash in case something fails.
- Sockets and voltage
- The voltage is 220 V at 50 Hz. Sockets of types A, C and I are found, so a universal adapter is useful, especially for American plugs.
- Emergency numbers
- Police: 110, ambulance: 120, fire service: 119. Save your hotel address in Chinese so you can explain yourself faster when asking for help.
- Time difference
- China uses a single time zone, UTC+8, with no daylight saving. The difference from Kazakhstan is three hours: it is three hours later in Beijing than at home.
- Language
- The official language is Chinese (Putonghua). English is found in large hotels and airports, but the odds are lower on the street and in taxis, so a translator and addresses in Chinese are useful.
- Payments
- In cities, paying by card outside hotels and big shops doesn't always work. The main way is Alipay and WeChat Pay QR codes, which need mobile internet.
- Wi-Fi
- Public and hotel Wi-Fi follows local restrictions, and logging in often requires a phone number. If a service doesn't open, turn off Wi-Fi and use your eSIM data.
- Water and tipping
- Tap water is usually not drunk: buy bottled water or boil it. Tipping is not customary in China and people usually don't leave tips in restaurants.
- Trains and airports
- High-speed train tickets are bought online, and stations and airports usually check electronic documents at the entrance. Download tickets and addresses in advance so they open even with a weak signal in a tunnel or at an underground station.
