What it really means
The check before departures where your bags are scanned. Standard UK rules: liquids in containers of 100ml or less in a clear bag, laptops out (at most airports), belts and big coats off. Staff say things like "any liquids or laptops in the bag?"
Chinese explanation
登机前的安检，行李要过扫描。英国常规要求：液体每瓶不超过100毫升并装入透明袋，笔记本电脑取出（多数机场），皮带和厚外套脱下。安检员常问"包里有液体或笔记本电脑吗？"
