This book tells the ordinary and unwilling life of Zhao Qiusheng, a left-behind child in Qingxi Town. He once cherished the dream of walking out of the mountains, but under the changes of the times and the pressure of life, he gradually became the most ordinary member of the vast sea of people. Tian Guyu, his childhood sweetheart, was regarded by outsiders as a "disaster" who would not survive more than three days, but he stubbornly survived with extraordinary tenacity. She was cold on the outside but warm on the inside, and became Zhao Qiusheng's only light in his darkest years. The two pulled each other apart amidst poverty, illness, and the tricks of fate. From being dependent on each other when they were young to drifting apart, they wrote a love-hate relationship rooted in the soil about growth, regret, and redemption.
