A wise man cannot succeed without learning, and cannot know without asking. "A wise man cannot succeed if he does not learn, and he does not know if he does not ask" comes from a famous saying in "Lunheng" written by Wang Chong of the Han Dynasty. It means that a person with wisdom and talent will not achieve anything if he does not learn, and he will not gain knowledge if he does not ask questions. He emphasized the importance of learning and asking questions, believing that only through continuous learning and asking questions can real knowledge and wisdom be obtained.
