It is rare to be confused, which means that people are rare to be confused when they should pretend to be confused. "It's rare to be confused" is a famous saying handed down by Zheng Banqiao during the Qianlong period of Qing Dynasty, and it is his own situation of being an official and life. Later generations felt that the word "rarely confused" was rich in philosophy, so they hung it at home in the form of banners as a warning for their daily life.
Zheng Banqiao's psychology and philosophy of life have both positive aspects, that is, he shows the stand and backbone of different evil forces in collusion with each other; There is also a negative side, that is, he who sees through the world of mortals is pessimistic and detached. What is shown in "rare confusion" is more negative and detached thoughts.
