Learning is labor, which is full of thoughts.
Wisdom comes from diligence, and genius lies in accumulation.
The edge of the sword comes from sharpening, and the fragrance of plum blossoms comes from bitter cold.
Learning is a sweet fruit that grows on bitter roots.
If you don't accumulate steps, you will be thousands of miles away; If you don't accumulate small streams, you won't be a river.
There is a road in the mountain of books, but there is no limit to learning the sea.
When the book is used, I hate it less. It's not difficult. Let's talk about it later.
