唐朝著名诗人李白小时候从不认真读书,经常是把书本一抛就出去玩耍。一天李白碰到一个白发苍苍的老婆婆正拿着一根大铁棒在石头上磨,觉得好奇问她做什么,老婆婆告诉他要磨成绣花针,李白深受感动,从此就用功读书,终于成为文豪。

Long ago, there was a famous poet who lived during China's Tang Dynasty. His name as Li Bai and it was said that when he was young, he did not like studying. He would often abandon his classes to play outside.

One day, he met an old lady who was grinding an iron bar against a stone. Curious, he asked her what she was doing. The old lady told him that she wanted to make a needle from the iron bar. Moved by her perseverance, he became determined to return to his studies with renewed focus.

Thus the saying, 只要功夫深,铁杵磨成针 (With perseverance, even iron can be ground into needle), became a Chinese proverbial saying.
