Even if you don't read Chinese, this set of photos should be self-explanatory. Except that the first two photos need some explanation. It was the story of how the author went to school when his hometown was flooded when the Yangtze River overflowed in 1998.
I guess that that experience inspired him to compile this series of photos from the web.
These pictures document the dangers that children face while going to school in some parts of China, Colombia, India, Indonesia, Myanmar, the Philippines, Sri Lanka, and somewhere in the Himalayas. The last pictures came from Jerusalem in 2010.
