Who can tell me the history of floods in Weinan, Shaanxi?

Weihe River, the largest tributary of the Yellow River, has watered Qinchuan's 800-mile fertile land for thousands of years. However, since the end of August this year, the rainfall in the western part of Guanzhong has been 4 to 8 times more, and it has rained for a month in just 8 days. The Weihe River, which has always been docile, was angry, and the raging river roared and attacked Linwei District, hua county, Huayin, Tongguan and Dali in Weinan City. Heavy rains and floods have brought great disasters to the Weihe River, which spans 800 miles of Qinchuan. More than 200 square kilometers of land was flooded, 6.5438+0.02 million mu of farmland was damaged, 6.5438+0.9 million houses collapsed, and 430,000 livestock and poultry drowned. But there is also a rare miracle: more than 5 million people on both sides of the Weihe River are safe and sound, and only one village party branch secretary and one reporter died heroically in the flood fighting.
