Wow!!! At least you've got blue sky and sunlight. I spent a week in Chengdu a month ago, the best days looked like this through the smog.
The two afternoons that I transitted Beijing's airport, it was early afternoon both times and it looked like twilight. Visibility was less then a mile (ie. less then one run-way's length.) When we flew out, we didn't break out of the smog until 15,000 feet!
