The master's answer about Xia Zi is as follows:

1.

Shang Bo (507 BC-400 BC) was born in Wen Yi, Nanyang County (now Buyangmen Village, Huangzhuang Town, wen county City, Henan Province). At the end of the Spring and Autumn Period, a thinker and educator was listed as one of the "Seventy-two Sages of Confucius" and "Ten Philosophers of Confucius" and was honored as a "tonic".

Xia Zi's character is gloomy and brave. He is good at being kind to others and learning from Confucius, so he is known as a "literary master". He used to be the county magistrate of Jufu, and put forward the idea that "being an official is the best way to learn, and learning is the best way to be an official", and advocated that "being an official can win the trust of the people and then make the people obey". After the death of Confucius, facing the chaos of Confucius, he went to Wei to teach and educate people, accepted Wu Qi as a disciple, and was honored as a master.

Xia Zi was not as strict with Confucius as Yan Hui and Zeng Shen, but he was a thinker with a tendency to study the world. He no longer attached importance to the restoration ceremony, but kept pace with the times and put forward a set of political and historical theories to continue the Confucian orthodox political views.

2. Main achievements

In history, the Book of Changes written by Confucius disciple Bu and the Book of Changes of Xia Zi have been handed down from generation to generation. Scholars are controversial about some issues of Xia Zi's Yi-ology. For example, is Xia Zi Yi Zhuan written by Xia Zi or Han Ying? This paper makes a preliminary investigation on the records of ancient books, and holds that The Book of Changes in Xia Zi does have the appearance of ancient changes, and it is indeed a divination, but Han Ying is not.

On the other hand, Xia Zi is not only familiar with the ancient meanings such as "image number" and "divination", but also can inherit the "keeping its virtue" advocated by the ancient meanings, and deepen the correspondence with the "new meaning" of philosophy, which shows the ideological characteristics of Yi's adherence to "ancient meaning" and compatibility with "new meaning". There are also classics in summer and summer, each with its own emphasis.

He is especially good at poetry and music, and once wrote Preface to Poetry. He also studied Shangshu, but not as good as him; He is good at the book of changes, and today's Confucius biography of the book of changes is likely to come from Xia biography; He is good at studying mourning clothes in etiquette, and he is the author of "Biography of Mourning Clothes". In the study of Chunqiu, the two versions of Gong and Gu, which give full play to the subtle meaning of Chunqiu, are all Xia teachings.

Studying Confucian classics in summer is good at discovering the subtle meaning of Confucian classics. Confucius' words are not full of meaning. He arranged and edited the Six Classics, which reflected his own thoughts and ideas. Confucian classics handed down in summer played a key role in promoting Confucius' theory.
