Confucius compiled the most important books in Shang Dynasty, didn't he?

No, Confucius mainly sorted out the classics of the Zhou Dynasty, specifically Zhouyi, and then wrote a book, Chunqiu. There seems to be no other works. The Analects of Confucius was written by his disciples, not his work.

In addition, the Xia dynasty advocated simplicity, the Shang dynasty advocated ghosts and gods, and the Zhou dynasty advocated humanism. Confucius didn't talk about Machamp's confusion, so he didn't specialize in sorting out books of Shang Dynasty. The Analects of Confucius also describes: I can speak in Yin, but I can't sign in Song. It means that I can understand and express the culture of the Shang Dynasty, but the cultural materials of the Song Dynasty-the continuation of the Shang Dynasty-are not enough for textual research. It can be seen that this matter did not settle at that time.
