Here is an interesting image showing Silhouettes in different shades.
The image shows how busy Guangzhou can be, with lots of activities on the bridges crossing the Pearl River in Guangzhou Chinese.
People and cyclists hastily crossing the bridges.
Nearest to us is the steel truss bridge with the truss members in silhouette.
Further away is the Jiefang Bridge (Liberation Bridge), with its bow string shape – arches in each river crossing span with cables suspending from the arches to support the bridge deck.
Of course, you can also see the Pearl River and some buildings in the background.
Again, thanks to my friend CP Chan who provided this interesting image.
