Later, people borrowed Mencius' famous words and jumped out of the history books. They only said that "it is better to believe in books than to have no books", and they all talked about books. In other words, when reading any book, don't swallow it blindly, but have the spirit of questioning and criticizing and think independently. In fact, it is very difficult to do this. You are knowledgeable, experienced and thoughtful.
