In 1994, the Three Gorges Dam, a symbol of China's hydraulic engineering prowess, began to take shape. Over the past decades, the mega project has intercepted floods nearly 70 times, diverting over 220 billion cubic meters of water to protect downstream areas. CGTN's Sun Tianyuan visited the Three Gorges Reservoir area in central China's Yichang to explore how its flood control system has ensured swift and effective emergency responses, safeguarding downstream communities during extreme weather events.
