Ports along the Yangtze River handled over two billion tonnes of goods between January and July this year. But how do the huge cargo ships navigate what was once a dangerous and unpredictable river?

In this episode, we meet engineers and technicians who explain how the ship lock, and the Three Gorges Dam, have helped in everything from transport to drought and flood prevention.
