Final episode tonight of Simon Reeve's adventures around the rivers of the world... funny he didn't come to see the Liffey or the Shannon isn't it? Missing out, so he is. Tonight he travels all the way to China for a trip along the Yangtze, Asia's longest river and the third longest in the world. His first stop is Dazu, where he sees thousands of ancient rock carvings that managed to not get destroyed under communist rule. He also visits the Three Gorges Dam - the biggest power station on the planet - before ending his journey in Shanghai. Not a bad old life that Simon has, is it?
