In the Qing Dynasty, Wu Chucai and Wu Diaohou compiled and selected nearly 800 ancient poems in the thirty-third year of Kangxi. The language of the selected article is concise, short and pithy, and it is a masterpiece that has been passed down through the ages, from which it is not difficult to see the editor's meticulous and thoughtful vision. The title of the book is Guanzi, which is selected from ancient Chinese literature. Its meaning shows that the intention of compiling this book is perfection. This book can "perceive" ancient prose at a glance. There are also some improper selections in this book, because the selections mainly focus on the formulation strategies during the imperial examination, but as an introduction to ancient Chinese prose, it still has its existence value.
