There is not a vanishing point in the above photo, but the buildings appear smaller farther away. That’s probably accurate: Chonqing is huge and the urban area extends as far as you can see.
The next one,taken a couple of years earlier, is downstream from Chongqing city. The water is brown because of flooding, when the river runs normally it is green.
I have always loved the elegance of cable stay suspension bridges. When I was in college, a very, very long time ago I was part of a team that built a model cable stay bridge that won a contest (a nerdy kind of contest where you were judged on things like displacement and strength over weight, as opposed to total weight, although there was a minimum load it had to bear.) These bridges along the Yangtze reminded me of that.
