It tells the story of Chen Yu, a college student who graduated in 2005, who was assigned to the remote Qingquan Town and found a way out in the fog at the grassroots level. He witnessed the subsistence allowance list being appropriated by relatives of village cadres1, risking his life to rescue trapped children on a rainy night but was involved in the whirlpool of public opinion2, and even found three times the inflated cement unit price in the dilapidated house renovation ledger3. At the same time, the suspicion of his girlfriend Lin Yue and the admiration of primary school teacher Xiao Qing plunged him into an emotional decision. The threats and inducements of Zhao Mingde, director of the Poverty Alleviation Office, opened bloody incisions in the dirty transactions of the grassroots power field. When an anonymous reporting letter pierced the corruption network, Chen Yu had to make the ultimate choice between his conscience and his future - should he be a mediocre official who goes with the flow, or should he be a foolish old man who shakes the mountains?
