Tool: Square yellow colored paper.

1. Fold the center line of colored paper in half, turn it to the back, and then fold the diagonal line in half.

2. As shown in figure 1, fold the bottom corner upward according to the crease.

Turn the corner in front of us to one side. We fold the corner in, turn it back, and then do the same thing on the other side.

4. Fold the upper two corners outward respectively.

5. Fold the upper corner in half and align the edge line.

For children, origami games have many benefits. Origami can exercise the flexibility of children's fingers and develop their hands-on ability and innovation ability; Things in life, small animals, vehicles, etc. Become an image origami.

Some sanatoriums use origami as a treatment for patients' rehabilitation.

The "origami mathematics" derived from origami art is proved by equations: theoretically, any geometric form can be simulated by origami. With the help of computer software aided design, today's origami researchers can fold more complicated graphics than before.

In Kamiya Satoshi, a 2m× 2m square paper was folded into a dragon, and its scales and claws were clearly visible. It is said that there are probably no more than 20 successful origami people in the world.

On the other hand, modern origami is not only an art, but also a new science: origami mathematics. It has been applied to the solar panels of artificial satellites, the storage methods of automobile airbags, and even the structural design of the Hubble Space Telescope, all with the help of origami mathematics.
