Things that can't fly are:
1, guns and controlled knives must not be carried with you, nor can they be simulated, and military police are no exception (nor can they be checked), depending on safety issues.
2. Fireworks, firecrackers, lighters and other flammable items must not be carried (or checked).
You can't carry alcohol with you, but you can check your luggage.
4. Many girls will bring cosmetics, but don't bring too much. They should be controlled within the range of 100ml (the total capacity is within 100ml), not the content, but the volume capacity of the bottle, and they should be packed in sealed bags (the same is true for medicines and oils). If it is exceeded, it should be checked.
5. Personal batteries such as mobile phones, cameras, notebook computers and video cameras can be carried with you, but they cannot be checked.
6. Small scissors, fruit knives, razors, eyebrow trimmers, kitchen knives and other household knives must be checked.
