On our way to the Guilin airport, we stopped to visit a farming village. In China, your destiny is to a large degree determined by where you're born.
If you are born on a farm, a farmer you must stay; you cannot easily move to the city as jobs and housing there are reserved for those born in the city. If your family is able to pay the $40 US a year it costs to go to school and you do well enough, you may be able to go to university and become a professional. That's about your only chance to escape a farmer's life.
