Geographical location of Dadu River:
Located in the midwest of Sichuan Province, People's Republic of China (PRC), it is historically regarded as the largest tributary of Minjiang River, a tributary of the Yangtze River in China. Dadu River originates from the southern foot of Guoluo Mountain in Anima, Yushu Tibetan Autonomous Prefecture, Qinghai Province, and its upstream source is Zumuzu River (the upstream source is Marco River and Ake River, which are in jiuzhi county). Aba County, after accepting Mosuo River and Chusijia River (Duke River and Duoke River) in Marcand County, is called Dajinchuan, which flows southward through Jinchuan County and Danba County, and then receives Xiaojinchuan in the east of Danba County, which is called Dadu River.
The historical significance of Dadu River;
Dadu River Cable Bridge is one of the existing ancient cable bridges in China. Also known as Luding Bridge. Located in the west of Luding County, Sichuan Province, it spans the Dadu River. In the forty-fourth year of Qing Emperor Kangxi (1705), construction started in September and was completed in April of the following year. The bridge has a clear span of 100 m, a clear width of 2.8 m, and a bridge deck distance of 14.5 m from the low water level. The whole bridge * * * adopts 13 iron cable chain, 9 of which are used as load-bearing bottom cables, and the bridge deck is covered with horizontal and vertical boards, which can pass people and animals; 4 as handrails, arranged on both sides of the bridge deck. The east and west abutments are made of stone, with a height of more than 20 meters. There are a bridge pavilion, a "Luding Bridge" plaque inscribed by Emperor Kangxi of the Qing Dynasty and an inscription on Luding Bridge. The anchor pit is located behind the abutment, with a width of 2m, a length of 5m and a depth of 6m. Eight pig iron piles are buried vertically, and another 1 anchor pile with a length of 4m and a diameter of 20cm is placed horizontally on the iron pile, and 13 iron chain is tied to the anchor pile. The iron cable bridge of Dadu River is an important passage from Sichuan to Kangzang Plateau, which is famous for its arduous project of building and repairing rapids between cliffs. ; On May 29th, 1935, the Chinese Red Army of Workers and Peasants captured Luding Bridge with surprise soldiers on the way to the Long March, and the Red Army crossed the Dadu River. Mao Zedong's poem "Long March" has the sentence that "Jinsha River is warm when it hits clouds and cliffs, and Dadu Bridge is cold when it is separated by iron cables". After 1950, it was repaired many times, and an exhibition hall was established to show the historical materials of the Dadu River Railway Bridge. Now it is a national key cultural relics protection unit.
