Record of the Southern Crossing Farming War: I Was Engaged in Infrastructure Construction in the Southern Song Dynasty

In the second year of Jingkang, the Northern Song Dynasty was destroyed, the mountains and rivers were broken, and the Southern Song Dynasty was established, and the situation was precarious. Chen Ji, a doctor of modern agriculture, traveled through Chengnan and Lin Yue, a descendant of the clan who fled to the south, and together with the like-minded Zhan Ziyan, shouldered the mission of revitalizing China. Lin Yue relied on modern scientific knowledge to start infrastructure construction in remote fishing villages in Zhejiang and Zhejiang. He improved the Song plow, promoted composting technology, experimented with high-yielding sweet potatoes, organized the reclamation of terraced fields, and established "mutual aid farms."

As Lin Yue's power grew, Song and Jin Dynasties faced off against the Huaihe River, and his "Southeast Foundation" prospered. At this time, Lin Yue opened household registration to attract northerners to move south, promoted "land to the tiller", and led the militiamen to cross the Yangtze River and expedition north.
