Daqinghe Shuai Li Yumei

He was a famous capable minister, honest official, and capable minister of flood control during the Daoguang period. He is called "Nan Lin Beili" by the people. He is a close friend of national hero Lin Zexu. He was a Jinshi in the same discipline as Tao Shu, the leader of the Hunan Army. Academicians Qi Zhuanzao and Tang Jinzhao praised him. He is Li Yumei, a native of Hunyuan, Shanxi, and an official during the Jiaqing and Daoguang years of the Qing Dynasty. He has been engaged in river management work for many years and has rich experience in river management. His official position was river governor. The River Governor is responsible for the prevention and control of the Yellow River, Huaihe River, and canal. Although he is not a feudal official, he has a high position and has always been a good job. At that time, the Yellow River and the Huaihe River flooded almost every year, especially during the rainy season. It was common for the river water to surge and destroy the dams. Therefore, it has also caused irreparable heavy losses to the production and life of local people. Based on this concept of river control, Li Yumei almost overturned all the water control experience of his predecessors, adopted the method of taking advantage of the situation and adapting measures at any time, and then achieved remarkable results in river control. In fact, the water control policy summarized by Li Yumei is very similar to the water storage and release of floodgates in later generations. Of course, Li Yumei has also developed unique methods of river management, such as "throwing bricks to build dams", which are all innovative.
