Teenagers work hard all their lives, so don't be lazy about time.
The ancients learned nothing, and it takes time to grow old.
Reading breaks thousands of volumes, and writing is like a god.
Ask where the canal is so clear, because there is running water at the source.
A lazy youth, a lousy age.
Once the youth is gone, it will never come again, and you will never see the arrival of the next day. Timely encouragement, time waits for no one.
Don't listen to things outside the window, just read sage books.
The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.
Learn not to explore its flowers, but to dig its roots.
After ten years' hard work, I have grinded out a sword. The edge of the sword flashes in cold light, but I haven't tried its sharpness.
Therefore, you can never get tired of reading books, and you are self-aware when you read them carefully.
The river runs to the sea, and when will it return to the west? If a person doesn't work hard when he is young, he will regret when he is old ―― laziness when he is young will make him regret when he is old; Reckless youth makes regretful old age; Idle youth, poor old age
Wise people cherish the short days, but sad people know the long nights.
Don't be idle, you are white-headed and sad.
