what the
Boat on the Yangtze River. What is this stuff? I have cranked up the contrast. Here’s the original. Sulfur? The contrast was quite stark with the brown water.
Aside: during a day trip to the Three Gorges Dam [about a month back], one of the bus-tour operators asked everyone ‘why is the water so brown?’ This gentle, ~70 year old man from Guangzhou yells out “POOP!” Smiling, the tour operator explained that the red/brown color was actually due to sedimentation [doubt that's *all* there is.]
It is good, however, to know that scatological fascination continues to be a relevant mode of discourse no matter how old and respectable one becomes.
Yup, looks like sulfur in the original.
sulfur or cornmeal. or maybe sulfur-infused cornmeal. or yellow egg tempera paint powder. i bet there are a lot of kindergartens in china, but do chinese kindergartens use tempera paint like the american ones?
