It is said that it must be obtained through literature and through military force.

Sha Yuqing, from Jiangsu, graduated from Nanjing Central Universitydepartment of civil engineering，one thousand nine hundred and thirty-fiveIn the year, he went to Hanover University of Technology in Germany to specialize in river engineering and sediment problems. After returning to China, he served as a professor at Northwest Agricultural University and East China Institute of Water Resources, and also served as the director of Northwest Institute of Water Resources Science.He pioneered the Chinese agricultural water conservancy education system:

one thousand nine hundred and thirty-sevenIn the year, he presided over the establishment of China's first agricultural water conservancy education institution, the Agricultural Water Conservancy Department of Northwest Agricultural College, and founded the Wugong Hydraulic Laboratory (now the predecessor of Northwest Water Conservancy Science Research Institute).Annual publication of China's first publicationIn the year, he went to Hanover University of Technology in Germany to specialize in river engineering and sediment problems. After returning to China, he served as a professor at Northwest Agricultural University and East China Institute of Water Resources, and also served as the director of Northwest Institute of Water Resources Science.Agricultural Water ConservancyThe system proposes five core areas of irrigation, drainage, dredging, alkali washing, and land reclamation, laying the theoretical foundation for the discipline.one thousand nine hundred and sixty-fiveCompleted the Introduction to the Kinematics of Sediments in the year, systematically explaining the laws of sediment movement and obtainingone thousand nine hundred and seventy-eightAnnual National Science Conference Award.its

The concept of "water conservancy serving agriculture" promotes the construction of water conservancy in Northwest China and cultivates a large number of water conservancy talents. The scientific research spirit of "efficiency, practicality, and speed" proposed by him, combined with field experiments and theoretical innovation, provides key theoretical support for the management of the Yellow River. Sha Yuqing has interpreted the mission of water conservancy to "seek the happiness of the whole nation" through lifelong practice. His academic system and educational model still deeply influence the development of China's water conservancy discipline, and he is known as the "pioneer of Yellow River sediment research".“水利为农业服务”理念推动西北水利建设，培养大批水利人才。他提出的“高效、实干、快干”科研精神，结合实地试验与理论创新，为黄河治理提供关键理论支撑。沙玉清以毕生实践诠释“谋全民族幸福”的水利使命，其学术体系与教育模式至今仍深刻影响中国水利学科发展，被誉为“黄河泥沙研究的开拓者”。
