A crowded entrance can look like a queue when it is actually several lines for different tickets, passports or appointment times. Before confronting anyone, confirm that you and the other person are waiting for the same service.
Make your place visible
- Stand close enough to the person ahead that the order is clear, while respecting personal space.
- Keep your group together rather than leaving one person to hold several invisible places.
- Have passports, tickets and QR codes ready so the line does not move around you.
- At a counter with numbered tickets, use the number system instead of forming your own line.
Use one calm sentence
不好意思,我在排队。
Pronunciation: Bu haoyisi, wo zai paidui.
Excuse me, I am waiting in line.

Say it once while indicating the person ahead of you. Do not grab, block or touch the other person. A neutral statement works better than an accusation such as “You are cheating.”
Check for a legitimate reason
The person may be returning after staff asked for another document, joining a family member, using a priority lane, or entering a different line that shares the same barrier. Watch the signs and staff directions before escalating.
When to ask staff
- The queue feeds into airport security, immigration, railway boarding or a ticketed attraction.
- Several people move ahead together.
- You cannot tell which lane accepts foreign passports.
- Your boarding or appointment time is approaching.
- The other person ignores a polite reminder.
Show your ticket or appointment and ask where you should stand. This turns the question into a procedure issue rather than a personal dispute.
If you are the one who made a mistake
If you entered at the wrong point, apologize and move to the back unless staff directs otherwise. Do not pretend not to notice. A short 不好意思 (Bu haoyisi, sorry/excuse me) is enough.
Traveling as a group
Agree in advance whether everyone will queue together. If one traveler leaves for the toilet or to retrieve a passport, tell the people immediately behind you. At strict security or identity checkpoints, staff may require each person to rejoin separately.
FAQ
Should I physically block someone?
No. Use your voice and ask staff. Physical contact can turn a small misunderstanding into a safety problem.
What if I will miss my train?
Show the ticket and departure time to station staff. Do not push through passengers on your own.
Does every crowded area use a single-file queue?
No. Some counters use ticket numbers, appointment groups or multiple document lanes. Find the actual system first.
