World-famous books were the most precious treasures of culture. What was the most difficult book to understand in the world?
There was no definite answer to this question because different people might have different standards for understanding a book. However, some books are considered one of the hardest to understand in the world because they may involve certain cultural backgrounds, historical backgrounds, language structures, or other factors that make them challenging to read and understand. For example, books such as A Short History of Humanity and The Galaxy Empire might be difficult for readers without relevant background knowledge and cultural attainments to understand the profound thoughts and philosophical implications. Some ancient classics such as Tao Te Ching and the Book of Changes were also considered difficult to understand and digest because of their profound philosophical thinking and ancient cultural value. The most difficult books in the world vary from person to person, but some classic works may involve certain cultural backgrounds and knowledge, and readers need to have a certain level of accomplishment and background knowledge to understand.
