There are fields that are not cultivated and books that are not read.
The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.
Young people don't know how to study hard, and old people regret studying late.
Explanation:
If the field is not cultivated, the granary is empty, books are not read, and future generations are ignorant.
The sharp edge of the sword is obtained from constant sharpening, and the fragrance of plum blossom comes from its cold winter.
If you don't know how to study hard when you are young, it will be too late to study again when you are old.
Extended data evaluation

In fact, the full text expounds a very simple causal relationship: when the granary is full, there is a field to cultivate; If you want your children and grandchildren to be smart, you must study; If you want a sharp sword, you must stand the test. If you want plum blossoms to smell fragrant, you have to endure the biting cold!
Diligence is good at diligence, barren is good at playing; If you want to have precious qualities or beautiful talents, you need constant efforts, cultivation and overcoming certain difficulties before you can succeed or perish.
