Can Shenyang Taoxian Airport stay overnight from June 5438 to February 2022?

You can't. Although Shenyang Taoxian Airport is also a public place, it is a special public place. There are many passengers getting on and off the plane, and the security of the plane is very strict. Security personnel will clear the area regularly or irregularly according to the flight schedule, and all stranded personnel without relevant procedures will be cleared out of the airport lobby. Overnight is not allowed. If you need to spend the night at Taoxian Airport, you can choose hotels around the airport or rest at McDonald's in the airport lobby.
