Li Bai was a great poet in the Tang Dynasty of China.

It is said that in his childhood, he was very fond of playing and afraid of difficulties, andmade slow progress in his studies.

One day, on his way home after school, he walked by a creek and saw an old womangrinding a very, very thick iron rod.

Being curious, he went to the old woman and asked:“Old grandma, why are you grindingthis iron rod?”

The old woman replied: “To make a needle.”

At this moment, Li Bai felt more curious and asked again:“How can you grind such a thick iron rod into a needle?”

“Yes, I can. I certainly can,”the old woman said. “If one works with constant effort, onecan grind an iron rod into a needle.”

Hearing the old woman’s words, Li Bai was enlightened.

Since then, Li Bai studied hard and made rapid progress. Eventually he became a famouspoet.
