The ancients left no stone unturned in their knowledge, and their kungfu only matured when they were young (Song Dynasty. Lu You. "Winter Night Reading Shows Ziyu")

Mechanics is like hard work, and you know yourself if you are diligent and lazy. But if there are many kinds of books, there will be good times. . ("Academy" by Liu Guo of the Song Dynasty)

Don't be in a hurry when reading, and you will be more interesting when reading. You may as well let it go if you don't know, but you need to think about it urgently. ("Studying" by Lu Jiuyuan of the Song Dynasty) The trees fell into the water and thousands of cliffs withered. However, I also saw the true self. Sitting facing the moving wall with Wei weaving lanterns, singing loudly as the snow falls on the hut in the middle of the night. The ground stove, tea cauldron, and fire are used to cook the fire, and everything is clear enough to be called a scholar. Where can I find the joy of reading? Count the plum blossoms in the world. (Yuan Wengsen's "The Joy of Reading in Four Seasons" Winter) Reading in spring brings long interest, grinding the inkstone and making the pen fragrant. Don't be lazy when studying. The world, the sun and the moon are busier than people. Yanyu and Yingge hope to understand, and peach blossoms and Li Bai write articles. (Spring in Xiong Boyi's "Reading Song for Four Seasons" in the Republic of China)

That should be: diligent study is like a seedling that rises in spring. If you don't see its increase, it will grow every day; dropping out of school is like a whetstone. If you don't see its loss, it will grow every day The loss... ——Tao Yuanming

It means: Diligent study is like a spring seedling. You cannot see it growing taller, but in fact it grows taller every day.

Putting down studying is like sharpening a knife. You can't see a stone getting thinner. In fact, the stone is getting thinner every day.

It encourages us not to relax in learning. As long as we persist, our knowledge will grow.
