Speaking of cultures all over the world, of course, China ranks first for thousands of years. Since ancient times, the development of China culture has experienced many setbacks and tests. Today, with the development of science and technology in Xun Gao, the history and culture of any period are worthy of our pride. Many scholars with great wisdom have emerged in these history, and their works have not been fully understood so far. Just like Shan Hai Jing, Huangdi Neijing and Yijing, each of them contains a lot of wisdom.

1. Shan Hai Jing is the oldest fantasy book about geography, medicine, mythology, folklore and religion in China, which is divided into mountain classics and sea classics. And these two main parts are subdivided into many categories. Shan Hai Jing is a book written by people of different times, and its author has different views. There are so many things described in Shan Hai Jing that many celebrities think it is absurd to deny their authenticity. Mr. Lu Xun is one of them. However, this book has not been completely preserved, and only 18 articles are left. Moreover, many magical places in the book have never been seen by everyone, so this book has always been considered a mystery.

Second, the wonderful book of medical skills "Huangdi Neijing" If you want to mention the wonderful book of medical skills, the first book is Huangdi Neijing. This book is the earliest medical work in the history of China. It was created at the same time as Shan Hai Jing. This book is very well preserved. There are many medical knowledge and health preserving methods in the book, which are precious wealth accumulated by the ancients through long years. Until now, it has been of great help to our medicine, geography, meteorology, biology and so on. Because the content is too profound, it has not been fully studied so far.

Third, the most difficult book If you want to say which book is the most difficult to understand, it must be the Book of Changes. The book of changes contains the great knowledge of everything in the world, called? The source of the avenue? . The Book of Changes consists of Lianshan, Guizang and Zhouyi. Now only the Book of Changes has survived. However, the content of the Book of Changes is very extensive and profound. From the Warring States period to the present, many scholars have spent their whole lives studying, but they don't understand its content, including respected writers, such as Nanhe. So the Book of Changes has left us too many mysteries and is the most difficult book to understand.

The ancients used their wisdom to write a series of profound works. Because of their extensive content and long history, many books are difficult to study. These seemingly simple ancient characters contain profound mysteries, and no one can study them thoroughly until today. At the same time, these cultural treasures left by the ancients are inexhaustible for us from generation to generation.
