Smog in
New York Times correspondent Edward Wong retweeted this photo by Wang Jinghua of CFP, and CNN chief national security correspondent Jim Sciuto noted: "If smog blocks out the sun, throw up a video of it."
Note that they didn't just put up this video because of the smog - this is a digital commercial screen that offers the best view of the sun there is.
Here are a couple of the screens:
