Three scholars took to the streets to catch the exam and passed a temple. Thinking in this story refers to repeated thinking and exploration. From Wang Chong's Lun Heng Yi Xu in the Han Dynasty: Gao Zong was afraid of terror and walked sideways, thinking about the administration of the former king. Once upon a time, three scholars went to Beijing to catch the exam and passed by a temple shop, asking the monk to calculate whether they had passed the exam. The monk closed his eyes slightly, thought for a moment, and held out a hand to show that he would not talk. Three scholars did not understand the meaning of a finger and asked for an answer. The monk touched his head: this is a secret and must not be revealed. I know the future. Can a monk really predict the future? Of course not. But this word can reasonably understand the various results in the future.
