During the Tang Dynasty, the famous poet Li Bai was not a diligent student in his youth. He often threw aside his books to go play.
One day, Li Bai encountered an old woman with white hair who was grinding a large iron rod on a stone. Feeling curious, he asked her what she was doing.
The old woman told him she was trying to grind it into an embroidery needle.
Li Bai was deeply moved by her perseverance. From that day forward, he studied diligently and eventually became a renowned literary master.
