The origin and original use of kites

The original use of kites: transmitting information.

The origin of kites: "In the Five Dynasties, Li Zheng made paper kites in the palace, led kites to ride the wind as a play, and then used bamboo as a flute to make the wind enter the bamboo, making it sound like A Zheng, hence the name kite." So those who can't make a sound are called "paper kites", and those who can make a sound are called "kites".
