Lin Qingguo, a college student village official, came to Yushu Village with ideals, but in his first class on a rainy night, he saw the true face of power - the account book in which poverty alleviation seeds were transferred, the seven overlapping thumbprints, and the local specialties that appeared at the door of the dormitory late at night. From forging project visas to manipulating academic reviews, from the false accounts of tea oil cooperatives to the secret boxes of offshore trusts, he has been ups and downs in the officialdom for twenty years. When he stood in the Beidaihe conference room and heard the word "shuanggui", he suddenly thought of the old farmer who was soaked all over. This novel restores the rules of survival in officialdom in astonishing detail. It is both a step-by-step guide for promotion and a shocking report on the pathology of corruption. When the moss is lifted, not only darkness is revealed, but also humanity twisted in the gears of the system.
