Hongyan Chen, 39
Mother-of-two Chen ekes out a living in Shenzhen, China's premier manufacturing city in the south, recycling the tons of garbage produced by rapid development. She earns 20 cents for a kilo of plastic bottles and $1 for every 100 paper sacks. It's dirty, exhausting work, but she makes just enough to survive, she says. It's a legacy of communism that Chinese women pitch in with manual labor as much as, if not more than, men.
