Li Qingshan, a doctor from the Academy of Modern Agricultural Sciences, came to the troubled feudal era of successive droughts and the collapse of order, and became a poor farmer in Taoyuan Village. He used modern knowledge to farm and animal husbandry, and gradually accumulated survival capital. He first made up for his debt to his wife Li Yueniang, then recruited refugees, expelled bandits, and established Taoyuan Village, rallying people with food and water and leading the villagers on the road to prosperity.
