Extended data:

Origami originated in China, and its history can be traced back to 583 AD. When Buddhist monks went to Japan from China via Korea, they took a lot of paper with them. Because paper was expensive at that time, they used it with extra care, and origami became a part of etiquette communication. Since then, origami art has been passed down from generation to generation.

Origami can stimulate people's creativity and logical thinking, and promote the coordination of hands and brains. In its decades of development, modern origami technology has reached an unprecedented level through the unremitting efforts of a new generation of origami experts. It is hard to imagine that a complex and lifelike origami work can be folded from a square piece of paper that has not been cut at all.

Therefore, modern origami is no longer just a children's game, but also a challenging and inspiring physical and mental activity. Scientists use paper to fold complex patterns, and skillfully deform the paper without glue and scissors. The final works are far from simple boxes or flowers, but realistic animals and paper sculptures, such as squid, snakes and dancers.
