Once upon a time, there was a little bird that liked to jump and fly on the branches. One day, the bird met a fox. The fox asked the bird,"If you like flying so much, why don't you become a pilot?" The bird thought for a moment and replied,"A pilot needs to have enough wisdom and skills. I'm just a bird. I don't have enough ability to learn these." "Don't worry," said the fox."I can teach you a way to become a good pilot." The bird was very happy to hear this, so the fox taught the bird how to fly and how to land. He also told the bird,"Only by learning these skills can you establish yourself in this world." The bird soon learned how to fly and land. It was very grateful for the fox's guidance. But one day, the bird met a bear and asked the bird,"If you are so good at flying, why don't you become a pilot?" The bird thought for a moment and replied,"A pilot needs enough courage and wisdom. I'm just a bird. I don't have enough ability to learn these things." "Don't worry," said Bear,"I can teach you a way to become a good pilot." The bird was very happy to hear this, so the bear taught the bird how to fly bravely and wisely. He also told the bird,"Only by learning these skills can you establish yourself in this world." The bird soon learned to fly bravely and wisely. It was very grateful for the bear's teaching. But one day, the bird met a hunter who asked the bird,"Why don't you become a pilot if you're so good at flying?"
