This sentence comes from Hanshu: The Book of Songs says that "there are many scholars, and Wang Yining has literature", and Confucius said that "a city with ten rooms must have loyalty", which is not empty talk. Your majesty caught everyone in the world and stuck it in the four corners when he died. He is almost ignorant, and he is advised not to tell the truth.

What you said is translated into vernacular Chinese: The Book of Songs says that "because there are many sages, the king of letters can enjoy the world", and Confucius said that "there must be faithful people in a small town ten miles away". These are all true. Your majesty, with such a vast land in the world, how can there be no pillar to stick to the four borders? The reason is probably that the road to talent promotion is not wide, the selection and appointment are not clear, and the encouragement is not sincere.

The "Wu" here should be a negative adverb, which means "no"
