The Yellow River has been cut off for the first time in Lijin County, Shandong Province in 1972. By 1996, it had been cut off 57 times for 682 days. Since this year, it has been cut off 10 times! As usual, the cut-off is hidden in May and June, but this year it starts on February 7, and the first cut-off is 15 days; It took 122 days in 1995 and 136 days in 1996. In 1994, the cut-off reach reached Chenqiao near Kaifeng, Henan Province, with a length of 683 km, accounting for 87% of the total length of the downstream reach. The cut-off caused increasingly serious sediment deposition in the downstream. The riverbed 780km below Zhengzhou increased by 10 cm every year. The fish at the estuary decreased, the desertification and salinization became more and more serious, and the ecological environment was damaged, resulting in a loss of about 26.8 billion yuan in industry and agriculture.
