Madan is a poor and backward small mountain village in the Chishui River Valley. As a supporting teacher at Matan Primary School, Ren Zheng was deeply influenced by Lu Xun's thought of "save the children". Ren Cheng is Bai Nanshan's first teacher. Ren Zheng's departure plunged Bai Nanshan into a life of disaster. Bai Nanshan and Zhi Youran were childhood sweethearts, but Zhi Ruo (Zhi Youran's sister) fell in love with Bai Nanshan by mistake. After the relationship between the two broke up, Bai Nanshan established a relationship with Zhi Youran. After graduating from high school, Zhi Youran went to Shanghai to study medicine, while Bai Nanshan went to Panshui Normal University. The two began an eleven-year long-distance relationship. Bai Nanshan took the opposite path to his original intention and became a teacher, quit his job and founded a media company. After experiencing the epidemic, company bankruptcy, death of relatives, relationship crisis and other hardships, he finally found himself.
Bai Nanshan finally decided to return to Madan to build and promote his hometown. Zhi Youran gave up her high-paying job in Shanghai and chose to go with Bai Nanshan.
