The Dayan Dynasty was a foregone conclusion in response to the Tianfu Rural Examination. Lu Yu, the child of the Lu family who was known as a playboy, seemed to be completely transformed in the examination room. He wrote the answer sheet, and his thoughts flowed like a fountain. The examiner, Mr. Liu, held Lu Yu's paper, frowned, and rubbed it carefully. This policy paper quotes from classics and is very informative. It especially discusses the border troubles in the north and puts forward the strategy of "replacing relief with work and guarding the border", which is a strategic plan. However, in the poem next to it, there were strange words such as "Lie down and let yourself be laughed at", which puzzled him. It is rare to find such a work that can be appreciated by both refined and popular people.
