What does the story of Confucius and Xia Zi tell me?

Xia Zi, surnamed Bu, patriotic and gentle, was one of the proud disciples of Confucius in his later years. Xia Zi was the first person to teach Confucian classics systematically after Confucius. He made great contributions to the spread of Confucian literature and the development of academic thoughts, and was praised as the originator of Confucian classics by later generations. Xia Zi has also made great achievements in the development and innovation of Confucianism. In his later years, he taught in Xihe area of Wei State. The "Xihe School" he founded trained a large number of outstanding statesmen and became the cradle of the growth of early legalists. Xia Zi has made outstanding contributions in spreading Confucian classics, carrying forward Confucianism, inheriting and developing Confucius thought, and cultivating characteristic disciples of Legalists.

But up to now, the research on Xia Zi is far from enough. This paper aims at systematically sorting out Xia Zi's academic and ideological contributions, summarizing Xia Zi's great achievements in China's academic and ideological history, and making the world understand Xia Zi's historical contributions more comprehensively and clearly. This paper is mainly divided into six chapters. The first chapter introduces Xia Zi's research achievements and main viewpoints so far, which are divided into three aspects: Xia Zi's national and family background, the relationship between Xia Zi and Confucian classics, and Xia Zi's academic and school. Judging from the current research situation, although a lot of achievements have been made in general, there are still many problems that have not been solved;

According to research, Xia Zi was born in 507 BC, entered Confucius at the age of 15, and followed Confucius around the world until his death. During this period, he used to be a guardian and father. After the failure of efforts to maintain the unity of Confucius Group, he left Lu and returned to Wei to set up accounts and collect disciples, and continued to spread Confucianism until his death. Throughout Xia Zi's life, apart from his short political career and mourning for his parents, most of his energy was devoted to the study and teaching of Confucianism.
