The Four Books and Five Classics are classical works in ancient China, including The Great Learning, The Doctrine of the Mean, The Analects of Confucius, Mencius, The Book of Changes, The Book of Books, The Book of Rites, Spring and Autumn Annals, etc. In traditional culture, these classics are regarded as the words and deeds of saints, and are important references in morality, philosophy, politics, etc.
According to the traditional writing standards, the four books and five classics cannot be labeled. This is because in ancient writing, the book name number is a symbol used to identify the book name, while the Four Books and Five Classics themselves are classics without a book name. In addition, the four books and five classics have a special status and are regarded as the classics among the classics, which is different from other general books. Therefore, there is no need for the title number to distinguish them.
In modern publications, in order to facilitate readers to find and quote, the four books and five classics usually add "" and "" before the title of the book, which is to distinguish it from other books. However, in formal academic papers, it is still necessary to abide by the traditional writing standards and not use the book name.
In short, the Four Books and Five Classics are classical works in ancient China, and cannot be titled. This is due to the traditional writing norms and the special status of classic works.
