A calligrapher asked a child to buy his paper. What allusions did he get after spending the money?

A calligraphy tutor practiced calligraphy, and a student who often practiced calligraphy with waste newspapers said that he practiced for a long time, but he didn't make much progress. The calligrapher said to the students, "Try to use the best paper instead.

"The student did as he said. Sure enough, it didn't take long and made great progress. The student asked the calligrapher what the reason was, and the calligrapher said, "When you practice calligraphy with waste newspapers, you always feel that you are making a draft, even if it is not well written. Anyway, there is plenty of waste paper, so don't pay special attention to it; "Practice calligraphy with the best paper that makes you feel distressed, and you will devote yourself wholeheartedly to practice, and your progress will naturally be great."
