Brief introduction of dazhi river

From Luhui on the east bank of Huangpu River to Donghaikou, there is an east-west waterway artery that runs through Minhang District and Nanhui District. It is a big branch, which has left a glorious page in the history of water conservancy in Shanghai and is called the mother river by Nanhui people. Standing on the highway bridge that flies over the Dazhi River like a rainbow, looking eastward, the grand scene of dredging Nanhui River for many years, especially when excavating Dazhi River 25 years ago, can't help but reappear. 1977, in the first winter of dazhi year after the downfall of the gang of four, the unprecedented campaign of dazhi river-digging project in Nanhui water conservancy history started. More than 300,000 migrant workers, more than 6,000 cars, small and medium-sized tractors and more than 2,000 unicycles in the county rushed to Hetian in the cold wind. Although the weather is extremely cold, migrant workers live in grass shops or temporary sheds not far from the river, but the red flag hunts on the river stretching for dozens of kilometers every day, and the horn sounds loud and powerful songs and victory news from various water conservancy groups from time to time. During the years from 1977 to 1979+05438+08, Shang Tang was completed. The army of 300,000 migrant workers completed 38.82 million cubic meters of earthwork and spent more than 56 million yuan. Finally, a river that shocked China and foreign countries was successfully excavated. For more than 20 years, Dazhi River has not only played an important role in flood discharge, irrigation of fertile fields and water delivery of Huangpu River, but also is the only river channel for domestic water consumption of 700,000 people in Nanhui. In recent years, it has become the awareness and conscious action of the people in the whole region to make the Dazhi River "distinctive" forever. Dazhi River-forever mother river.
