What was the previous sentence?

It is clear to the beholder that the former sentence is a mystery to the authorities. From Liu Shao's Biography of the Yuan Dynasty in the Old Tang Dynasty: "The authorities are fascinated, but the bystanders are clear." This is a metaphor that the parties to a matter often think too much about gains and losses, and their understanding is not comprehensive, but they are not as clear as the onlookers. At first, it means that when playing chess, the two sides can't see the situation clearly, but the bystanders can see the essence of the game clearly from the perspective of a third party.

Some people don't know the true face of Lushan Mountain in Su Shi's Title of Xilin Wall, but toward which corner of the mountain. Similar to the meaning that the authorities are fascinated by the beholder. Being in the middle of Lushan Mountain, the view is limited by the peaks of Lushan Mountain, and what you see is only one peak, one ridge, one hill and one valley, which is one-sided and inevitably one-sided. This is what you see when you visit the mountains, and it is often the same when you observe things in the world.

Extended data:

The idiom "The spectator is clear" comes from The Biography of Old Tang Shuyuan, which is judged by authoritative people. In the Tang Dynasty, there was a learned man named Yuan Lian, whose words were very bold. He wrote Thirty Dian Wei, which was praised by many scholars at that time. On one occasion, a minister visited Xuanzong of the Tang Dynasty, demanding that the Book of Rites revised and compiled by Wei Zhi, a famous figure in the early Tang Dynasty, be listed as a Confucian classic. Tang Xuanzong thought it was a good idea, so he ordered Yuan Hangchong and others to check it carefully and add comments.

After a period of time, Yuan Hangchong completed the task, organized Wei Zhi's notebook into fifty articles, annotated them and presented them to Xuanzong. Unexpectedly, right-wing Prime Minister Zhang said that he had different opinions. It occurred to him that Dai Sheng's book had been used for nearly a thousand years now, and Zheng Xuan of the Eastern Han Dynasty also annotated it. Why did he use Wei Zhi's book instead? Xuanzong thought what he said was reasonable and changed his mind. However, Yuan Hangchong thinks it's better to change a notebook. He wrote an article called "Explaining Doubts" to show his point of view. This article was written in the form of a dialogue between the guest and the host.

The guest asked, "Which book is the Book of Rites?" The host replied, "This book compiled by Dai Sheng has been revised and annotated by many people since the Western Han Dynasty, and there are many contradictions. Considering this situation, Wei Zhi revised and sorted it out. I don't know if people who stick to the rules will object! " The guest said, "It's like playing chess. The players are confused, but the onlookers can see it clearly." ?
