The arrangement order of the four books and five classics

Four Books: Also known as the Four Books, namely, The University, The Doctrine of the Mean, The Analects of Confucius and Mencius; Five Classics: Poetry, Calligraphy, Ceremony, Book of Changes, Spring and Autumn Period. Refers to Confucian classics.

Source "White Tiger Tong Five Classics": "What are the Five Classics? Also known as Yi, Shangshu, Shi, Li, Chunqiu. " Song Zhuxi took notes on four books.

The Four Books and Five Classics are the basic bibliography of Confucianism after the Southern Song Dynasty, and they are also required books for Confucian students.

Personally, I think this is related to what Zhu Cheng's Neo-Confucianism advocated at that time.
