To let his wife and daughter live a stable life, Lu Changqing takes Jiang Yuhe and his daughter Lu Xiaoxiao away from the big family, taking over the Heishipo mountain field and a dilapidated mountain guardhouse. He is able to establish cooperation with the mountain and forest animals, using food as reward to ask squirrels to forage for mountain goods, wild boars to till the land, crows to transmit messages, and black bears to transport, never forcing the animals to take risks. His wife Jiang Yuhe manages accounts and develops sales channels, and the couple runs the mountain goods together. After life stabilizes, they help fellow villagers sell mountain goods, adhering to communication and consultation when encountering conflicts. Supporting each other, the family runs the hard barren mountain life better and better through diligence and integrity.
