Lunheng·Shujie" said: "There are things that are flashy but not real, and there are things that are real but not flashy." It means: some things are gorgeous in appearance but not good in substance, and some things are good in substance but not flashy. Not beautiful in appearance. This world is like this, where blessings and misfortunes depend, and misfortunes lie on blessings. The ancients used the word flashy to describe people who are superficial and have no inner self-cultivation, so I think it should be a derogatory word in that era. Our ancestors were ashamed of this.
