Yang Jinshui was sent by Emperor Jiajing to Zhejiang to manage the Weaving Bureau. In 1566, Daming had a deficit in the national treasury and planned to change rice into mulberry in Zhejiang. This national policy was good at first, but as a result, Yan Shifan was confused and corrupted, which led to problems in the whole national policy. And the role of Yang Jinshui was sent by the palace, so he is a living evidence. He has an account book in his heart, and everything happened in it is clear, so when Harry came to check it later, Yang Jinshui knew something was going to happen.

The reason why eunuch Yang Jinshui pretended to be crazy:
There is something wrong with the policy of changing rice into mulberry in Zhejiang. The higher authorities began to deal with this matter. First, Zhao Zhenji was sent down by the imperial court to inspect it. The following two people need to cooperate with Harry, so the upper one in the imperial court was killed, and the lower one, Zheng He He Maocai, was also killed, Shen set himself on fire, and Hu Zongxian was dismissed. All the people who came into contact with this matter are dead now, even their adopted son is dead.
So Yang Jinshui knew that the living ledger in his mind was a big problem. At this time, he plays the fool, knows nothing and won't say anything. This is the best way to save himself. If you don't want to die, it won't help much, so you can only pretend to be crazy, and pretending to be crazy means you have to experience a more painful life than death.
