Jia Lu, a native of Gaoping, Shanxi Province in the Yuan Dynasty, was smart, studious and ambitious when he was a child, but he was knowledgeable and resourceful when he grew up. He used to be a professor of Confucianism in Lucheng County, director of Yin Hu Department, and also participated in the compilation of History of Song Dynasty. Later, he served as an inspector, a doctor of the Ministry of Industry and a water supervisor, during which he presided over the flood control of the Yellow River many times. It is said that in order to find out the cause of the flood, Jia Lu traveled thousands of miles along the Yellow River waterway to explore the terrain and water potential. With long-term on-the-spot investigation and years of experience in river management, he gradually accumulated a set of his own "general plan for managing the Yellow River".
In the fourth year of Zheng Zheng (1344), the Yellow River changed its course in Baimaodi, Cao County, Shandong Province, and flooded more than ten counties in Henan, Shandong, Anhui and Jiangsu provinces. In the following years, people on both sides of the strait had to leave their homes and lead miserable lives. In the 11th year of Zheng Zheng (135 1), in April, 55-year-old Jia Lu was appointed as the minister of the Ministry of Industry and the general river defense ambassador, recruited15,000 migrant workers and 20,000 soldiers from Henan Province, and started a massive river regulation project. He adopted the method of dredging and blocking at the same time, that is, while dredging the old channel and tributaries of the Yellow River and excavating new channels, he blocked gaps and gaps and built dams. He also used the sinking method for the first time to tie 27 large ships together, fill them with stones and fix them on crevasses, then dug holes in the hull to sink, and finally blocked the crevasses and forced the water back to the old channel. By 1 1 month, all civil works had been completed, which was a success for many years. This is the famous "Jia Luhe" in China's history of harnessing the Yellow River, and Jia Lu's name is recorded in history.
