Yanzi Chunqiu is the oldest collection of legendary stories in China. Some people regard it as the earliest biography, "although there is no name of biography, it is also the ancestor of biography." Others think that it is China's first collection of short stories and the origin of China's novels. This book details the life anecdotes, legends and anecdotes of Qi Linggong, Zhuang Gong and Qi Jinggong sage Yan Ying, and was written in the Warring States Period. According to the narrative content, the historical stories recorded in this book can be divided into three categories: one is the historical stories in Zuozhuan and other books, but they have been processed to varying degrees; One is a political story about the experience of governing the country and securing the country, which mostly appears in the form of political dialogue between Yan Zi and Qi Jinggong; One is a legendary story about Yan Zi's ruling activities and daily life, which also includes some chapters that laugh at the prince and satirize the yes-men. This part accounts for the largest proportion. This book successfully created the earliest characters of various personalities in the history of China literature. Yan Zi in the book is a person with superhuman wisdom, caring for the people, integrity and incorruptibility. This image is basically consistent with historical facts, but there are differences, and the author has made artistic treatment. There are more than 200 short stories in the book, which are interrelated and complement each other, forming a vivid and complete image of Yan Zi. First of all, Yan Zi is a typical loyal minister and saint. Most of the stories in the book describe Yan Zi's remonstrance with the monarch or the monarch's questions about political affairs, from which we can see that Yan Zi is a ruthless exposer of feudal tyranny and monarch's evil. Secondly, Yan Zi is a typical wise man. Many stories describe his legendary superhuman wisdom and astute eloquence. The well-known story of "Yan Zi controls Chu" is very representative. At the same time, he is an unpredictable warlock. Yan Zi once again became a model of honesty. He is impartial, determined to be rich and strong, and indomitable. After the "Cui Yao killed Jun" incident, he ignored the threat and "sat naked, cried and rejoiced on his body and came out three times." Righteousness, do not lose its ambition. He is in a high position and has made outstanding achievements, but he lives a very poor life, wearing "clothes" and eating "nothing to eat" and living a "near the city and noisy" life. The language style and expression of this book are superb, the language is bright, simple and humorous, and the dialogue between characters is full of personality characteristics, especially the sense of humor permeated in the characters' language, which not only makes the story interesting, but also increases the interest and enthusiasm of the language. The author is also good at using metaphors, some of which contain philosophy of life and later become independent languages or idioms. In a word, the book adopts the form of story collection, which integrates anecdotes, legends and anecdotes about Yan Zi, and this form has had a far-reaching impact on biographical literature of later generations.
