This time, he decisively puts the past behind him, refusing to repeat the regrets of his previous life. By chance, he rescues Su Qinghe, a female educated youth struggling through difficult circumstances, and her younger sister. Zhao Ye boldly makes a promise to them, and the two join hands, register their marriage, and start a family. Drawing on his skills, Zhao Ye works hard in the mountains to improve their living conditions, protecting his wife and sister-in-law from gossip and mistreatment. Working together with one heart, the couple steadily builds a better life, eventually constructing a brand-new brick house and protecting their warm little family. Amid the everyday bustle of the 1970s, they support each other and pursue the happiness and hope of ordinary people, writing a love story set in a bygone era.
