5am. I arrive in Shanghai from Singapore. Four hours until the flight to Korea. Do I leave Pudong Airport for a quick tour around the city? It’s probably too early for anything to be open. I end up befriending a fellow passenger while walking to our next gate. We stroll around the airport during our wait. The ceiling looks like worms sticking out and fighting over food (below). Appears cooler in photos than seen in person. Photogenic.
