Fan Shusheng is a transformed man, more eloquent and articulate today, says wife Zhang Xianfen.

It's not only his wife who thinks so. Says the 36-year-old migrant worker: "I used to think only about how to make a few more bucks. But now I've realized it's more useful to learn about what the laws have to say through TV and newspapers."

The skilled construction worker's articulation and sense of purpose and justice have helped many, and co-worker Yang Ruifeng is one of them. Yang says he got his arrear wages because of Fan's advise.
