Some Chinese peasants used to build outside toilet rooms and sties side by side. I wonder if that still is the omnipresent case nowadays and if the sanitation has improved.

On a different note, as more and more Chinese peasants have been bought out of 'their' lands and put into apartment-like buildings in more concentrated areas due to the frenzy real estate construction boom, will those areas soaked with ex-peasants become rundown slums further down the road, given that many ex-peasants and their children don't have sufficient education under their belts to prosper away from land?
