Generally speaking, if there are suspicious or unqualified items in the luggage, the security personnel will ask them to take them out for inspection. For example, some airports stipulate that it is forbidden to carry liquids, gels, sprays and other items exceeding a certain capacity. In addition, if you bring special items, such as medical equipment, medicines, etc., you need to consult the airline in advance and apply for the corresponding exemption. Airport security inspection refers to a personal and baggage inspection item that passengers on civil aircraft must accept before boarding, and it is also a necessary measure to ensure their own safety and the flight safety of civil aircraft in the air.
