He was accidentally involved in a suspicion of fraud in the examination room, and was invited by Marquis Yongning, who was in charge of the Ministry of Justice, to investigate the case. From then on, he worked step by step, passing through the various levels of the imperial examination, while assisting the marquis to solve many old cases.
