Wu Qiong, a university teacher, set up a paper mulberry cooperative in Xindian Village last year. He led the villagers to plant hybrid paper mulberry trees. He also invited experts from the Institute of Agricultural Sciences to set up a "field class", hoping to help some poor households through paper mulberry planting. get rid of poverty. But the villagers have their own minds and do not have a long-term vision. Li Desong has been planting paper mulberry for most of his life, and he doesn't care about the experts' lectures. They built a mold room privately, and took up some work to slowly pay off the debt. The elder brother Li Tieguang is idle all day, and the farm work at home is handed over to his daughter Li Caihong, who is still in elementary school. The field class that was finally set up was turned into a farce by the sheep running around in Li Tieguang's house.
