Does Gong Yu belong to folk literature? Gong Yu belongs to Shangshu and has been defined as a fake book by scholars.

The concept of folk literature seems inappropriate. Even if The Book of History and Yugong is a fake book, it is still historical data, because it may not be of great significance to the study of the era represented by the Book of History, but it is still valuable to the people's ideas of the era when its book was produced. After all, it is an ancient book, but it remains to be determined whether it is a fake book, whether it is a complete fake book or a partial fake book. In fact, some history books were entrusted by later generations, and now I don't know what the titles are.
