Last night my wife and I watched an excellent film on PBS, one of their "P.O.V." series. The film was called "Up the Yangtzee" by filmmaker Yung Chang.
"Up the Yangtze" explores the impact of China's Three Gorges Dam project by following two Chinese teenagers who work on a Yangtze River cruise ship. One is the daughter of an impoverished farmer, the other is a son of China's new middle class.
We thoroughly enjoyed this film and highly recommend it. You can check with your local PBS station to find out when it's being shown again. The website for the film can be found here.
