In a country where government censorship shuts down critical voices, how did former journalist Chai Jing break through to reach over 100 million people?
She brought the story home with a message any parent can relate to.
For Jing, the story started in Shanxi, a place that was famous for its vinegar. These days, Shanxi is famous for something else: It's considered one of the most polluted places in the world, a result of its massive coal mining operations. But people in China aren't as surprised to hear about the effects of pollution there anymore.
