Li Bai was a great poet in the Tang Dynasty of China. It’s said that in his childhood, he was very fond playing and afraid of difficulties, and made no effort in her studies. one day, in his way home after school, he walked by a creek and saw the old woman grinding a very, very thick iron rod. Being curious, he went to the old woman and ask, “Old grandma, why are you grinding this iron rod?” The old woman replied, “To making a needle.” At this moment, Li Bai felt more curious and asked again, “How can you grind such a thick iron rod that into a needle?” “Yes. I can. certainly can,” the old woman said. “If one works with constantly efforts, one can grind an iron rod into a needle.” Hearing how the old woman said, Li Bai was enlightened. Since then, Li Bai studied hard and made rapid progresses. Eventually he became a famous poet.
