"Deep in the Heart of the People" takes the young cadre Lin Yuan's ten years of grassroots experience as the main line and vividly records the legend of a small town civil servant's rise to power. The story begins when Lin Yuanchu, a transfer student, arrives in Qinglin Town. From college students who cannot understand dialects, to village cadres who eat and live with the masses; from novices who deal with neighborhood disputes, to practitioners who promote reforms; from confused young people facing temptation, to outstanding party members who stick to their original aspirations. The novel delicately depicts Lin Yuan's explorations in poverty alleviation, reform for the convenience of the people, ecological protection and other fields, and creates a typical image of a grassroots cadre in the new era. The work profoundly reveals the theme of "the grassroots is the biggest classroom and the masses are the best teachers". Under the words and deeds of old secretary Zhao Dashan, Grandma Li's affectionate entrustment, and Yang Laosi's simple wisdom, Lin Yuan refined his original intention, grew and transformed. From Qinglin Town to the county-level Development and Reform Commission, positions are changing, but the original intention of "serving the people" remains unchanged. The summary and promotion of "Qinglin Work Method" demonstrates the innovative practice of modernization of grassroots governance.
