Although there are good delicacies, you cannot eat them without knowing their purpose; although there are great ways, you cannot learn them and do not know their goodness. ——"Book of Rites·Xue Ji"

It means: Even though there is exquisite food, if you don't eat it, you won't know how delicious it is; even though there are good principles, if you don't learn it, you won't know how good it tastes. I don't know how wonderful it is.

If jade is not polished, it will become useless. If people don’t learn, they don’t know.

("Book of Rites")

Relaxation is the way of civility and military affairs. ("Book of Rites·Miscellaneous Notes")

"Book of Rites·Xueji": "That is why after learning, you will know your shortcomings. After teaching, you will know your difficulties, and then you can improve yourself."

After learning, you will realize your shortcomings; after teaching, you will realize your difficulties. If you know your shortcomings, you can then reflect on yourself;

If you know your shortcomings, you can then improve yourself.
