The Cao family kite craft is a traditional folk handicraft that has been passed down in Beijing to this day based on the kite atlas and rhymes recorded in the "Nan Yao Bei Yuan Kao Gong Zhi" of the Qing Dynasty. The book "Nan Yao Bei Yuan Kao Gong Zhi" summarizes 43 kite-making and pasting techniques, and summarizes the process into four arts: making, pasting, painting, and releasing. It uses kites as a carrier to reflect China's profound cultural connotations, and uses image aesthetics, anthropomorphism, and patterned expressions to reflect the high traditional cultural value. Cao family kites are made of bamboo, paper, silk, satin and other materials through processes such as making, pasting, and painting. This production technique has the characteristics of excellent material selection, delicate craftsmanship, bright colors, and beautiful shapes. It uses the principle of bionics and adopts a unique "rebirth" technique to make kites such as birds and animals, which are lifelike and reduce the weight of the kite. Cao's kite works are novel in style and diverse in variety, expressing contents such as historical allusions, customs and legends, folk customs, simulation and realism, etc., with distinct cultural characteristics of the ancient capital.
