Dadu River

The Dadu River , a tributary of the Yangtze, also known as the Tatu River, is located in the Sichuan province of China. The river is noted for being crossed by the Luding Bridge, a historically important bridge. It was the site of a famous battle by the Chinese communists over Nationalist troops during the Long March.

The Kangding Louding earthquake of 1786 caused a landslide dam in the Dadu. Ten days later, 10 June 1786, the dam broke and the resulting flood extended 1400km downstream, and killed 100,000 people. It is the second-deadliest landslide disaster on record.

A song from the Chinese ''The East Is Red'' is entitled "Across the Dadu River."

There is also a Dadu River in Taiwan.
