As the world's largest hydropower station with 26 hydropower turbo generators, central China's Three Gorges Dam has an inflow of 51,000 cubic meters and an outflow of 40,000 cubic meters per second. Why was the power station be built? What technical problems did the builders face during the design and construction phase? What breakthroughs have been to reach completion? China's Grand Canal also reigns as the world's longest man-made waterway. With more than 2,500 years of history, the Grand Canal exemplifies China's contribution to water conservancy projects. What lessons can we learn from these hydroelectric projects in China? How could we find the balance between exploitation and environmental protection? CGTN goes to the Three Gorges Dam and Grand Canal to find the answers.
