Today, I firstly give a brief introduction about Sun Zi and his book, The Art of War. According to The Historical Records He was a man of Qi and showed his book to the king of the State of Wu This is the introduction of Sun Zi In the Historical Records it only simply mentions his dates of birth and death without his succession of teachings from a master to his disciples And it also mentions that he was later the commander of the State of Wu Today , I’d like to add some more about him. Sun Zi lived in the end of the Spring and Autumn Period, and the dates of his birth and death were between 551BC to 479BC, which were deduced by later scholars based on his achievement mentioned in the Historical Records. What kind of contribution did he make? It is recorded in the Historical Records that “Wu defeated powerful Chu and entered Ying, the capital of Wu”. It is recorded in Zuo Zhuan that in 507 BC There occurred a severe war between States of Wu and Chu. The powerful Chu Army was defeated after five battles. Wu Army occupied Ying, the capital of Chu, which is now Jinyang in Hubei province. This is a great contribution he made. Then the State of Wu threatened the status of the States Qi and Jin” In 484BC, there occurred a big battle in Ailing between the States of Wu and Qi. In the end Wu won the battle. Two years later in 482BC Wu and Qi formed an alliance, and thus Wu took the place of Jin’s Hegemony, and became one of “Five Hegemonies in Spring and Autumn Period”. So we can see that when he served as a commander in the State of Wu he made remarkable achievements. This is the brief introduction about him in the Historical Records As to his family background and achievements, it tells us. a story about his life in the Historical Records. If fact, we are all familiar with the story nowadays. This story mainly tells us after Sun Zi offered his book to the king of the State of Wu, the king said he had already read it. Could you put your theory into practice on the spot? that is, he wanted to know whether the theory had practical value. Then, the king challenged Sun Zi, requiring him to train his concubines as soldiers in the palace. As we are all familiar with this story. I will not repeat it here. The story presents its historical authenticity. Today, all college students have participated in military trainings. We all know that an army drilling on the spot is similar to our military training. In our military training, {\fnSimHei\fs20\shad0\pos(200,280)}那么 an ordinary officer or a well-trained soldier is capable to finish this mission. So it is so unreasonable for the king to challenge Sun Zi with this simple task to select a commander-in-chief of armed forces. Consequently some people doubt the truth of this story, Sun Zi lived in the Spring and Autumn Period, and during this period, it was not popular for individuals to write their own books, that is to say there were few books written by individuals. That is the reason why we know little about Sun Zi nowadays. as to this detail record in The Historical Records, we think in a sense it was not real. So we leave a question open here, and then let’s talk about the book The Art of War. In “The Historical Records”, after the introduction of Sun Zi it also introduces another military strategists, Sun Bin a hundred year later than Sun Zi. It points out there is another well-known book of the art of war written by Sun Bin. Due to this record, It confused people who is the real author of The Art of War, Sun Zi or Sun Bin? In the process of research, many scholars kept doubting about it, and they had argued about it for over a thousand years until 1972 In the excavation of the mausoleum of Han Dynasty in Linyi of Shandong Province, a lot of bamboo slips were unearthed among which two precious books of The Art of War were found, one was written by Sun Zi Bing Fang , the other by Sun Bin. So based on these bamboo slips we are very clear about this question, That is, a thousand dispute disappears in a day, for in the same tomb, we found two well-known books of the art of war written by Sun Zi and Sun Bin respectively. So The Art of War we talk about was written by Sun Zi or Sun Wu living in the Spring and Autumn Period. The above is about the author of book,
