Up the Yangtze

Tonight Liz and I watched what sounds like a Carry On film, but was pretty much the opposite: a good but somewhat depressing documentary of a poor, uneducated family living on the banks of the Yangtze who send their 16-year old daughter to work on a cruise ship which plies China's longest river. It's also about how the reservoir formed by the Three Gorges Dam swallowed up towns, villages and livelihoods, including the family's ramshackle home. 
I don't know which was more depressing: the plight of the family or the big fat western tourists on the ship. Or the other new recruit whose only motivation was to secure as much tip money as possible, or the drab scenery. 
It was directed by Chinese-Canadian, Yung Chang. He 's also directed a film about Chinese boxers called China Heavyweight.
