In the first year of Chongzhen, famine was about to break out in the Taihang Mountains. As soon as Li Tian opened his eyes, he became the son of a run-down tenant farmer: there was no food at home, local bandits were outside, the government was demanding money, and the gentry was hoarding grain. When others robbed grain, he settled the accounts first - moisture-protecting terraces, mixed cultivation of beans and grains, grain storage in cellars, work points for grain stamps, and joint defense of fortresses. A mouthful of food saves a village, and a food road stabilizes a county. When bandits swept through and the borders collapsed, he discovered: In the late Ming Dynasty, only those who can feed people are worthy of talking about the world!
