This is a real-life novel that spans decades and focuses on rural changes and human warmth. The story begins in Guman Village, a barren and isolated loess mountain village in the 1970s. Gu Chen and Gu Mu, a pair of farm brothers, have different life paths of staying in their hometown and going to the city. They witness the earth-shaking revitalization of their mountain village through the ups and downs of ordinary people's half-life.
Gu Chen, the down-to-earth and responsible elder brother, is familiar with farming and people's conditions. He stayed in the village as a substitute teacher in the late 1980s, silently guarding the left-behind children in the mountains. City girl Li Xiaobei cherishes educational ideals and goes to isolated mountain villages to support education. She is not afraid of rugged mountain roads, difficult conditions and ideological barriers, and sticks to the rural podium. After spending time together day and night, she was deeply moved by Gu Chen's simple kindness and responsibility. She resolutely gave up the opportunity to return to the city, took root in the mountains and stayed with him for half her life, and used knowledge to illuminate the future of generations of mountain children.
The younger brother Gu Mu, who is talented and intelligent, is well aware of the poverty in mountain villages and has studied hard since he was a child. Taking advantage of the opportunity of the times, he got a gold medal, left the mountains, established himself in the provincial capital, and had a stable career and a new life. He lives in the city but never forgets his hometown, becoming his brother's most reliable external help in building his hometown.
Over the years, Gu Chen was elected as the village party secretary by the villagers, taking root at the grassroots level for decades. The two brothers, one guarding their homeland and the other exploring distant lands, work together to build their homeland inside and outside; the husband and wife hold hands and work hand in hand to deepen mountain education and grassroots construction.
After decades of ups and downs, the once barren and desolate loess village has transformed into a harmonious new village with green waters, green mountains and stable people's livelihood. The smoke from cooking fires lingers in the mountains, and two generations of ordinary people wrote the most simple and touching local epic with perseverance, dedication and dedication.
