There is still some time to check in at Yinchuan Airport. After checking the luggage, I saw a KFC. After the security check, there was no one inside. So I came to buy a cup of coffee first. This is a semi-open restaurant. Now it is a scan code order. There are not many people, so it is very fast. Airport stores generally charge more places, eat something here, rest, and then go to the plane, there are not many restaurants in the security check.
