Grand Master Shuiguan Jiangzha of the Northern Song Dynasty

During the Taiping and Xingguo years, Taihu Lake collapsed its embankments. Zhang Yan, a minor official from the Ministry of Industry, used hydrological measurements to predict the disaster. However, he was framed by powerful forces and demoted to Furongwei, a desperate situation. In a desperate situation, he used buoys to measure tides, gabions and wooden piles to fix the gate foundation, and created a "layered gate-sand diversion channel" hub to find a way out of the flood. Fortunately, the old river engineer Chen Mochuan, the Xiangjun Wu Huanhu for construction, and the grain merchant Shen Sitong made a fortune, and the three of them worked together to build the river gate and connect the canal to Toyota. Since then, his actions have not stopped: he built an "ice dam culvert" in northern Xinjiang to defend against the Liao cavalry, demolished the noble mansion in Bianjing to build drainage, regulated the Yellow River, and improved water transportation. Faced with doubts, Zhang Yan only said: "The gates can be destroyed, the books can be burned, and the 'principles' of managing water - the right way to remove blockages, and the distinction between public and private, should be preserved in the hearts of the people of the country." This is the story of the Northern Song Dynasty's technocrats who relied on water conservancy to create an epic. This novel and its characters are purely fictitious.
