Water calligraphy is one of my favorite activities to witness in China. During the early mornings, older men and women gather with large paintbrushes to draw Chinese characters on the ground, using water instead of ink to draw their lines. The writing is often political in nature but can also be ancient poetry or proverbs. I find it beautiful that they generate these masterpieces while fully aware their strokes will fade away within minutes. They seek to create their art, not record it.
I apologize for the insanely poor quality of this photo. I shot it while I was jogging in Xujiahui Park. I promise I wasn't just trying to snap photos of men bending over.
