Here is a small orientation to the city where we are living. You can see Nanjing on this map, close to Shanghai, right in the middle of China’s east coast.

Beijing is a good 1,000 miles to the north.
Nanjing is a good sized, modern city with 6.5 million residents, more or less the size of New York City. Here is a view of the skyline.

Here’s a closer view of the downtown buildings.

So is the haze in all your pictures of the cities pollution or fingerprints on your lens?
We have trouble ourselves trying to figure out which part of the haze is from the natural humidity (it’s going to be a hot summer), and which part comes from various pollutants. The air doesn’t smell too bad, but you tend to cough more on a daily basis here. One thing we see often is a street-side vendor burning garbage to cook their food. While this does recycle all the cardboard and paper we toss out, it can’t be all that good for the air quality.
How did it come to known as Nanjing from when I learned geography and it was Nanking?
