The title of the unearthed document, Volume 8 of Chu Bamboo Slips of Warring States in Tsinghua University [3], records the story of Yi Yin's "defecting to Tang Shixia" (leaving Shang Tang as a spy in the summer). Among them, "ancient" is a misinterpretation of the word "pigeon", and the correct title should be "red pigeon soup house"

Some scholars think that this article is a novelist's speech and a "pre-Qin novel", while others think that there was no novel concept in the pre-Qin period. Judging from the actual arrangement of pre-Qin classics and bamboo slips, it is inferred that this article, together with Tang Zaishimen and Tang Zaitangqiu, is a chapter of Shangshu and belongs to Shangshu in Qin Dou.

The story is full of ups and downs, lively and interesting. The relationship between the characters in the whole story is very complicated. Why design such a complicated relationship in a short article? I think this is the author's conscious creation of conditions for making up stories. There is also a very colloquial dialogue in this pre-Qin literature. For example, Tang's wife wants soup, and I said, "I can't give it to you, or the king will kill me." His wife said, "Can't I kill you if you don't give me a drink?" The question and answer is very vivid.

This story is obviously not a real event in history. It is at least a novel like Hanshu Yiwenzhi, and even thinks it has the characteristics of a novel in a pure literary sense like The Legend of Tang and Song Dynasties. The most important point is that this text has the aesthetic function of narrative literature. Whether this view can be established remains to be studied.
