The farm produces more crops than it sells, and the leftovers are donated to rural schools, according to Wang, who says he much happier working on the farm than being in an office.

Wang says he also hopes to begin raising predator insects and providing biological control methods to other farmers so they can grow crops organically.

Wang's father now also works on the farm and says he wants to support his son, even though he doesn't understand his career choice.
