Li Bai, a great poet of the Tang Dynasty, did not enjoy reading in his childhood. One day, taking advantage of his teacher's absence, he secretly slipped out of the house to play.
Walking to a small river at the foot of the mountain, he saw an old woman grinding an iron pestle on a stone. Curious and puzzled, Li Bai approached and asked, "Grandma, what are you grinding the iron pestle for?" The old woman replied, "I am making a needle." Li Bai asked in surprise, "Oh! The pestle is so thick, how can it be ground into a needle?" The old woman smiled and said, "As long as I keep grinding every day, the pestle will get thinner and thinner. Do I need to worry about it not becoming a needle?"
Hearing this, Li Bai reflected on his own behavior and felt ashamed. He turned around and ran back to the study room. From then on, he kept the principle that "Where there is a will, there is a way" deeply in mind. He devoted himself to reading with determination and eventually became a great poet, known as the "Poet Immortal."
唐代大诗人李白，幼年时并不喜爱读书。一日，趁老师不在屋内，他悄悄溜出门去玩耍。
行至山下小河边，他看见一位老妇人正在石头上磨一根铁杵。李白心中纳闷，上前问道：“老婆婆，您磨这根铁杵做什么？”老妇人答道：“我在磨针。”李白惊讶地问：“哎呀！铁杵如此粗大，怎能磨成针呢？”老妇人笑呵呵地说：“只要天天坚持磨，铁杵就会越磨越细，还怕磨不成针吗？”
李白听后，联想到自己，心中顿生惭愧，转身跑回了书屋。从此，他牢记“只要功夫深，铁杵磨成针”的道理，发愤图强，刻苦读书，最终成为了一位伟大的诗人，被誉为“诗仙”。
