"What you are looking at is Beijing Subway’s Line 13 on the morning of Thursday, July 18, around 7:30. It’s likely the Xierqi station — a picture of which, tweeted out by Joe Xu, we linked to on Friday — which is a transfer station and one of the cleaner, better-looking ones in the system," says Anthony Tao, who posted the video to the English-language Chinese blog, Beijing Cream.
"It has, like other stations in Beijing’s vast underground transportation network, built-in artificial bottlenecks intended to relieve congestion in the form of gates and narrow staircases," he explains. "On some occasions, however, those fail. For you see, in China, sometimes there are simply too many goddamn people."
