On a dusty road in China’s eastern province of Jiangsu, a slim, middle-aged man stood in front of an open truck and played an announcement through a speaker.
“Apples for sale! 1.20 yuan per jin,” the message repeated on a loop.
That's less than 20 cents a pound, which is cheap even for China. Guanyun County, some 300 miles north of Shanghai, used to consistently rank among the poorest areas in this province.
