Plot: 32-year-old Xu Han worked in Shanghai for eight years. He was exhausted and wanted to go back to his hometown. He went to the countryside to find his old classmate Shen Huange, met Du Xiaoyu, and fell in love at first sight. Shen Huan-ge has been secretly in love with Du Xiaoyu for ten years. Du Xiaoyu decided to resign and go home to start a Liulichang. Xu Han felt that running a homestay was good, so he rented the old house of Du Xiaoyu's family and started a homestay. Because Du Xiaoyu's father was greedy and burned all Du Xiaoyu's fruit trees with herbicides, Xu Han gave the idea of soilless hydroponics. At this moment, Shen Huan-ge was seriously ill, and he asked Xu Han to promise to laugh at Du for a lifetime. Xu Han's homestay has improved, and many people want to study, so they set up a homestay school. According to the market demand, Du Xiaoyu's orchard set up a chicken farm, and the villagers began to earn money and get out of poverty. Shen Huan-ge's body is getting weaker and weaker. Shen Huan-ge wants Xu Han and Du Xiaoyu to get married as soon as possible, and they promise Shen Huan-ge. In fact, Shen Huan-ge is made up to get sick, so that they can be together. The hotel and the chicken farm are getting better and better, and their feelings are getting deeper and deeper. They live a happy life between the green mountains and green hills.
