The history of origami:

Origami is an artistic activity of folding paper into various shapes. Through the combination of folding, folding, cutting, lifting, pulling and turning, origami transforms a planar two-dimensional space into a three-dimensional form with a three-dimensional space, realizes the size transformation of the space, and shows a sense of space and modeling. It has the advantages of simple design, rapid forming and wide application range.

There are two main views on the origin of origami art, namely, China's origin theory and Japanese origin theory. Generally speaking, with the development and spread of papermaking, origami began to appear in China, Japan, Arabia and Europe in the 7th and 8th centuries. It is said that the paper flowers unearthed in Dunhuang Grottoes are the earliest origami works in the world so far.

Arabs applied the original geometric principles to origami, studied geometry through origami, and linked origami with elementary space geometry, which promoted the development of both sides. The Spanish also learned origami in an earlier period and spread it widely in Europe. Japan's origami is the most prosperous, initially developed in Muromachi era, and gradually popularized in Edo era, forming the art and culture of origami, and giving birth to the world's first origami book, The Secret History of Thousand Feathers Crane Folding.
