In sight: Water - not everywhere and not much to drink

Walls without plaster, an entrance without doors, two raised parallel strips 0.3 m or so apart with an opening in the middle and a big container below. That is a toilet for 12-year-old Dilihumar and 400 other students of her school in a village near Taklamakan Desert in the Xinjiang Uygur autonomous region.

It is the same for most other people across rural China, where people are still hired to remove the night soil once every one or two months.
