Yang Zhaoyu quit his job in a big Chinese city nine months ago and moved to a small community that preaches sustainable living and mindful consumption.

"After graduating from college, I lived a very mainstream life," the 30-year-old former software developer said. "I dated, got married and found a job."

But Yang realized he wanted something different, so he ditched his career in Suzhou, west of Shanghai, and found a new life in an isolated community centered around sustainability and organic farming.
