The airport was large and disorganized and seemed to have no climate control of any kind. My family and I had a tour to see the Great Wall and scheduled a 10 hour layover to do so. However the immigration official, who was very unprofessional, had a mental breakdown and started crying when we finally got to the front of the line. She refused to let us into the country because she couldn't do her job. Her exact words were, "there is too many people here, I cant do this." My family and I then waited in the freezing airport for another 9 hours or so until we were finally able to get into the relative comfort of our airplane seats.
