The whole court knew that Lu Zheng would not listen to anyone.
Xiao Ce persuaded him, and he went in with one ear and out with the other. The emperor advised him, but he turned a deaf ear. Liu Yuan persuaded him, and he drew his sword directly.
Only when Shen Jinghan spoke, the stubborn donkey would calm down, listen, and then say: OK.
Someone asked Lu Zheng why. Lu Zheng said confidently: Mr. Shen speaks nicely.
Shen Jinghan spoke like everyone else, cold and emotionless, as if he was reciting official documents.
So there is only one conclusion: Lu Zheng likes to listen to official documents.
