What to pay attention to when flying, and what to bring

Take care of your valuables, adjust the flight mode on your mobile phone, fasten your seat belt, and you are not allowed to bring liquids or jelly objects on the plane. When you go through the security check, the security inspector will remind you. In fact, it is similar to making a car.

You can't bring water to check in by plane, so don't buy too much water while waiting for the plane. (and extremely expensive). Phone stays in airplane mode (haha, airplane mode finally comes in handy), too much luggage to post. Try not to bring too many things to check in.
