We weren't expecting this many lights in the city of Dujiangyan. It still stuns me that unlike most cities in Europe, Chinese cities love extensive night lights and since they are mostly LEDs, it's not even expensive.
I've never before seen rivers lighted up as well like this, only in China, but I think it's lovely and results in an entirely different atmosphere than without it.
