The Analects of Confucius is a record of words and deeds recorded by the disciples of Confucius, an ancient thinker in China and one of the top ten historical celebrities in the world. Written in the early Warring States period. Because Qin Shihuang "burned books to bury Confucianism" (although books were burned to bury Confucianism, some alchemists were actually buried alive), there were only books orally taught and obtained from the wall of Confucius' residence in the Western Han Dynasty.

There are: 20 pieces of The Analects of Lu orally taught by Lu people, 22 pieces of The Analects of Qi orally taught by Qi people, and 2 1 piece of The Ancient Analects found in the double wall of Confucius' residence. At the end of the Western Han Dynasty, yu zhang perfected The Analects of Confucius, and on the basis of The Analects of Lu and The Analects of Qi, he formed another theory called Zhang Houlun.
