Quick Answer
Security checks in China are routine, fast, and predictable.
You will encounter them at airports and major train stations, but they are designed for high volume and move quickly.
If you follow simple rules, the process is smooth.
The Core Reality (Why There Are Checks)
China’s transport system handles:
- Extremely high passenger volumes
- Long-distance daily commuting
- Dense urban networks
Security checks are part of normal operations, not a response to tourists.
Where You Will See Security Checks
You will pass security at:
- Airports (before check-in or boarding)
- High-speed rail stations (before entering waiting areas)
- Some large metro stations (light checks)
These are expected and unavoidable.
What the Process Looks Like
Typical steps:
- Place bags on an X-ray scanner.
- Walk through a metal detector.
- Occasionally respond to a brief question or manual check.
The process is usually under one minute per person.
Liquids and Electronics
Liquids
- Normal personal liquids are usually fine
- Large containers may be questioned
- Alcohol limits apply on trains and flights
If unsure, keep liquids accessible.
Electronics
- Phones, laptops, tablets are allowed
- Power banks are common
- Devices usually stay in your bag unless asked
Power banks must meet airline rules for flights.
Power Banks (Important Reminder)
For flights in China:
- Power banks must have clear capacity labeling
- Some airlines require 3C certification
- Unlabeled or damaged power banks may be confiscated
For trains, rules are more relaxed, but caution is still advised.
Documents and Identification
- Carry your passport
- Tickets are digital
- Passport is often scanned or visually checked
Keep documents easily accessible.
How Early Should You Arrive?
High-Speed Rail Stations
- Arrive 30–45 minutes early
- Boarding closes shortly before departure
Arriving too early is unnecessary.
Airports
- Domestic flights: arrive 90–120 minutes early
- International flights: follow airline guidance
This is standard practice.
What NOT to Do
- Do not argue with security staff
- Do not joke about prohibited items
- Do not rush the process
- Do not hide items intentionally
Cooperation keeps things fast.
Common First-Time Mistakes
- Arriving excessively early
- Packing prohibited items accidentally
- Letting phone battery die before checks
- Panicking at unfamiliar procedures
Everything is routine.
