Since the existence of human beings in the world, it has been constantly improving and moving forward. Humans are the most intelligent advanced animals in the world. Because they are good at inventing, good at creating. He also has super fantasy abilities and is intelligent. The ancients saw that birds have a pair of wings and can fly freely in the sky, so they are thinking, how can we humans have no wings, if we also have a pair of wings like birds, we can fly freely in the sky, how good would it be? Once someone woven wings with bamboo rods, mounted themselves, ran outside, with the help of the wind, also like a bird, kept flapping those wings, and finally flew up, flew in mid-air, and in less than a moment, it fell to the ground. People were all thrown. So they think it's weird? How come birds don't fall when they fly in the sky? We all have wings, so why can't we humans fly to the sky? Are they very, very confused? Confused? Very, very confused? Their wish has not been realized, but they have not given up on it, they have placed this unfinished wish on future generations, hoping that future generations can help them realize this wish? Is that a generation entrusted to a generation? From ancient times to the present, until now, the wish of human beings to fly into the sky has finally been realized, that is, the planes that are now said, and spaceships, which can carry human beings to fly in the vast sky and complete things that the ancients have never thought of for thousands of years? Finally, this good wish was achieved. They can henceforth rest in the ground and rest in peace forever!
