When the idealist Lin Weimin first joined the Development and Reform Commission of Jiangbei City, he encountered the first blow from reality: the pollution project ordered by the leader to "handle special matters," his colleagues' survival philosophy of "being in harmony with the light and the dust", and the sugar-coated bullets of businessmen... Should he go with the flow and integrate into this bottomless dye vat, or go against the current and get a bloody head and head? Obsession and belief, wisdom and skill, survival and ideal. This is a road of promotion full of thorns, and it is also a lonely self-cultivation. Lin Weimin chose the most difficult path: he studied the rules with concentration, but was not trapped by them; he was proficient in interpersonal communication, but was not bound by relationships. He used public opinion as his sword and political achievements as his shield, mediating between various forces in battles without gunpowder. From a section clerk to a chief official, his opponents range from cunning section chiefs to city leaders, and even higher... Not only must he solve development problems, but he must also face official corruption and protect fairness and justice.
