"The First Secretary of the Village" tells the story of Cheng Zhiyuan, a young expert from the Provincial Academy of Agricultural Sciences, who gave up the favorable conditions in the provincial capital and resolutely returned to his impoverished hometown of Yunling Village to serve as the First Secretary. Faced with the villagers' doubts, the complexity of grassroots work, and the temptation of developers' interests, he led young villagers such as Lin Xiaoyun and Zhang Lei to explore Qingyunling's wild tea tree resources, overcome the shortage of funds, technical bottlenecks, and human obstructions, combine traditional agriculture with science and technology, create the "Yunling Wuya" characteristic brand, and promote the revitalization of rural industries. In the process of leading the villagers out of poverty and becoming rich, Cheng Zhiyuan not only realized his personal value, but also gained his sincere emotions, and also made the ancient mountain village glow with new vitality in the wave of the times. This is a history of rural struggle full of blood and warmth, showing the responsibility and sentiments of young people in the new era to take root at the grassroots and dedicate their youth.
