In 2000, Lin Yuan, a master's degree student, entered the Municipal Environmental Protection Bureau with great ambitions, but was assigned to the Petitions and Complaints Office for refusing to follow unwritten rules. On the bench, he discovered the shady story of illegal discharges from chemical plants and took risks to obtain evidence, but was threatened with suspension. He gained support from the provincial department with his professional report, overturned the protective umbrella, and became famous in one battle. In the following two decades, he broke through the game of phasing out backward production capacity with an iron fist, found a new way out of the dilemma of river basin management, accurately lifted out of poverty in the fortress of deep poverty in impoverished counties, took the lead in the construction of smart cities, and took on the task in the face of the great test of the epidemic. From section clerk to deputy director, every promotion is accompanied by open and covert attacks, and every breakthrough demonstrates wisdom and responsibility. This is a workplace survival guide for civil servants, and it is also a song of adhering to the original intention and going against the current! See how Lin Yuan writes his own legend with hard work on this thorny road.
