The old woman said, "I am grinding the needle."

Li Bai was surprised and asked, "Oh dear! As thick as a pestle, how can it be ground into a needle? " The old woman smiled and said, "As long as you grind it every day, the pestle will become thinner and thinner. Are you afraid it won't be a needle? " Hearing this, Li Bai was ashamed of himself. He turned and ran back to the bookstore.

From then on, he kept in mind the truth that "as long as the kung fu is deep, the iron pestle is ground into a needle", studied hard, and finally became a great poet, known as the "Poet Fairy".
