In autumn, wild geese(大雁)fly to a warmer place. They fly in a V formation(队形). It makes them fly farther and more efficiently. When a wild goose leaves the formation, it will experience the difficulty of flying alone. Then, it quickly comes back to the formation to take advantage of the updraft in front of it. If the leading wild goose gets tired of flying, it will go to the end of the V-shape while another one takes the lead. This is how they share the leadership and support everyone in the team. If a goose gets sick and must leave the team, two others will stay with it to offer help and protection. They remain until it can fly again or it dies. They just make another V-shape. So they stay beside each other in times of difficulties and great challenges.
Let's learn from this story of teamwork. If we know the spirit of teamwork, if we understand the real value of teamwork, life will be easier and full of success.
