Intimidation and bribery are common tactics used by leaders, and Wu Keming is especially adept at these methods.
Wu Keming has long seen through people like Gao Shibao. Talented yet unrecognized, he's been hitting walls in society for years; his former sharpness and boldness have been dulled, gradually assimilated by reality. So, either inducement or intimidation is the most effective approach for such a person.
Sure enough, hearing Wu Keming's words, Gao Shibao was dumbfounded. Indeed, now that the other party had put clothes on, he really had no evidence. If it blew up, given Wu Keming's tactics, dealing with him would be a piece of cake. If he really got transferred to a suburban county, he'd probably have to spend the rest of his life stuck there!
