Lin Yi, 42 years old, is a senior investigator with the Anti-Corruption Bureau of a certain first-tier city. On the surface, he appears to be selfless, but in fact, in the past few years, in order to protect his seriously ill wife and son from attending international schools, he privately helped several businessmen "handle" marginal evidence and received "thank you fees." His wife is deceased and his 17-year-old son is preparing for the college entrance examination. He has been living in the self-consolation of "if he persists for a few more years, he will wash his hands in the golden basin."
