It is said that Han Xin, a general of the Han Dynasty, used kites to make measurements. Liang Wudi used kites to send messages, but failed. In the Northern and Southern Dynasties, someone jumped from a height with a kite on his back and didn't die. When Zhang Pi was besieged in the Tang Dynasty, he used a kite to send a message for help, which succeeded. These show that the history of kites in China is at least 2,000 years. Since the Tang Dynasty, kites have gradually become toys. By the late Tang Dynasty, kites had been made of silk strips or bamboo flutes, and the wind blew, hence the name "kite". Some people say that the name "kite" originated in the Five Dynasties, when Ye Li pasted a kite with paper and installed a bamboo flute on it.
