Apparently, there was a big "happening" in the museum case at the Forbidden City's Museum of Clocks. As soon as it was announced on the loud speaker, the case was mobbed. Being short, all I could see was the backs and heads of people. A clever lady using her selfie stick provided me with a camera-back view of what we were all trying to see.
Not really a vacation photo since I was in Beijing for work, but then, I was in four countries this summer, almost all for work.
