Due to historical reasons, the research fault was formed, which led to the loss of its essence. Only the river map, Luo Shu, congenital hexagrams, acquired hexagrams and sixty-four hexagrams are left. But when was this book written? Who is the author? Some people say it's Fu, others say it is, and opinions vary.

2. The Puzzle of Tutui is one of the most famous prophecies in China. According to legend, Li and Yuan Tiangang predicted the important events in the Tang Dynasty and later dynasties during the Zhenguan period of the Tang Dynasty. Sixty images in the book are named after sixty Jia Zi and hexagrams respectively. Because of its accurate prediction, it frightened the rulers of past dynasties and has always been listed as a banned book.

3. The mystery of the burning of Epang Palace For more than 2,000 years, the phrase "Chu people were burned to the ground" in Epang Palace Fu is evidence of the ultimate fate of Epang Palace. However, in the recent investigation by archaeologists, no traces of burning were found. According to legend, when Xiang Yu burned Epang Palace, it was probably just people's imagination. Epang Palace was never burned, or it was never built.

The unsolved mystery of Sanxingdui The discovery of Sanxingdui pushed the history of ancient Shu to 5000 years ago. Where does Sanxingdui culture come from? It is incredible that there are so many bronze figures and animals here, but not a word has been left.

Regarding the demise of the ancient Shu kingdom, people assumed various reasons, but they all stayed on the hypothesis because of lack of evidence.
