Once upon a time, there was a rabbit who always made fun of a slow tortoise. Tired of the rabbit's boasting, the tortoise challenged him to a race. The rabbit quickly ran ahead, leaving the tortoise far behind. Thinking he would win easily, the rabbit stopped to take a rest in the middle of the race for a short nap. But when he woke up, the rabbit saw the tortoise, who had been steadily crawling forward, was close to the finish line. Hurrying to catch up, the rabbit ran as fast as he could towards the finish line, but he couldn't make it in time. The tortoise had won the race with its steady perseverance.
