What is the content of Su Shu? Why is it called "gobbledygook"?

Sushu Rumors is a wonderful book written by Huang Shigong at the end of Qin Dynasty, which reveals the truth of the world. It contains the basis for China traditional literati to govern the country in a unified way, and guides us to understand what the origin of this world is. It is because of the magical and great content in the book that he was praised as? A gobbledygook .

In the third grade, I was very interested in this kind of ancient literature books, and then I bought one of these "plain books". At that time, I was amazed that the thickness of this book was really thin, and it was hard to imagine that it was such a thin book, which was praised as an ancient gobbledygook and a wonderful book in China. I have compared another classic book of China, which is also known as a fantastic book. It's caigentan. Compared with Tan Caigen, Su Shu was more unknown to me at that time. Therefore, I didn't study the content of this book carefully, because I just flipped through it. Now that I think about it, I still have some regrets.

I remember there is such a story in the extracurricular reading of primary school textbooks, which is related to Su Shu. This is the story of Sean and Huang Shigong. Because the assassination of Qin Shihuang failed, Sean was forced to flee, hiding his identity and saving himself. He happened to meet an old man in rags on the bridge. The old man was Huang Shigong, one of the five most influential hermits in China at the end of the Qin Dynasty, but Sean didn't know him at that time. Huang Shigong deliberately kicked his shoes under the bridge and asked Sean to help him pick them up. This was repeated three times to test Sean's personality.

Finally, Sean passed the exam, and then Huang Shigong passed this wonderful book to Sean. Sean lived up to expectations and successfully helped Liu Bang stabilize the country with this book. After Sean's death, he didn't pass this book on to future generations, but took himself into the cemetery as a funerary object. It was not until hundreds of years later that grave robbers dug up this book from Sean's tomb that it was reopened to the world. This book is Su Shu.
