Zheng Banqiao, known as one of the "Eight Eccentrics of Yangzhou", left behind two four-character famous quotes, one is "It is rare to be confused" and the other is "Suffering a loss is a blessing". Regarding self-cultivation, the latter sentence is undoubtedly more worthy of people's belief. Mr. Banqiao's famous saying "Suffering a loss is a blessing" is known to many people. During the New Year, visiting relatives happened to see a rubbing of "Suffering a loss is a blessing" hanging high in the hall. When I think about it carefully, how many people are actually willing to suffer a loss, and how many people really believe that "suffering a loss is a blessing"?
