To get by what - the Chinese police checkpoint?
True story, I have had to at an airport before while getting stopped by half a dozen cops before boarding an aircraft.
Am luckily a very calm person, as they were seemingly trying to break me by ordering me to sit down after having pulled me aside for a "routine inspection".
I would then get ordered to stand up, only to get ordered to sit down.
By the 4th time, my rage is boiling, but again--wrong country to say a thing in.
Softly and politely, while sniffling my anger:
"But sir, I was asked to sit down by this officer"
He angrily orders me to stand, only to then get corrected by the officer who had made the initial orders.
I then realized they weren't trying to break me. They had horrific communication skills.
All this for hesitating for a second about the precise price of the items inside my suitcase (gifts) (all legal), and had read up on all laws involving this so was breaking none.
Agent: "I want a specific number".
Me: (confused as to whether I had done something wrong): "Uh, about 600USD"
I would never go back unless I kept all receipts and calculated it prior to being at the airports if loaded with gifts, none identical to make it clear they aren't for resale.
