An excerpt from the article 12 facts about Three Gorges Dam
Sun Yat-sen, the first provisional president of the Republic of China, theorized about constructing a dam in Three Gorges to store the resources of the Yangtze River, and to improve the shipping route. His idea was then later re-evaluated by Mao Zedong, the founder of the People’s Republic of China, and the preparation for construction started in 1955.
