Also, there was a documentary put out recently called Up The Yangtze by Yung Chang. I've heard that its very good.

Here is the synopsis:

A luxury cruise boat motors up the Yangtze — navigating the mythic waterway known in China simply as “The River.” The Yangtze is about to be transformed by the biggest hydroelectric dam in history. At the river’s edge — a young woman says goodbye to her family as the floodwaters rise towards their small homestead. The Three Gorges Dam — contested symbol of the Chinese economic miracle — provides the epic backdrop for Up the Yangtze, a dramatic feature documentary on life inside modern China.
