What is the origin and significance of flying kites?

The true origin of kites is now impossible to verify. Some folklorists believe that the ancients invented kites mainly to miss the sophisticated relatives and friends, so when the death gate of Tomb-Sweeping Day was briefly opened, they pinned their sympathy on kites and gave them to the dead relatives and friends.

The earliest kites were not toys, but were used for military and communication. In the late Tang Dynasty, it was called "kite" because someone added strings to the kite, which sounded like a guzheng when the wind blew.

In BC 1000, people in China first flew kites. It is said that people in China could fly kites long before they believed in history. According to legend, in the 4th century BC, Lu Ban, a famous craftsman in China, made a kite and took off for three days without falling. There is also a story in which a general surrounded the palace and used a kite to measure the distance between the palace wall and his own army. Kites can be used to send bricks to and from home, or to tie hooks to the tail of kites for fishing. In 1600, oriental kites (diamonds) were introduced to Europe by the Dutch. /kloc-In the 9th century, the British inventor Clay was inspired by kites and invented the glider. Texas actor Cody "Captain" once used a kite to drag a folding boat across the English Channel. 190 1 year, I made persistent efforts to fly kites with double boxes, which aroused great interest from the British War Department. Soon, the plane replaced the military kite, and Cody, the "captain", died in an air crash while flying his new biplane on 19 13. 1970, the American space program designed various "flying wings" to make kites become toys for adults again. For example, the Rogge Lele folding flying wing was originally designed for the safe landing in the Mercury spacecraft cabin, and was later replaced by a parachute; But this folding wing was originally the wing of today's hang glider. Flying a kite provides the principle and inspiration for the plane to fly into the sky.

Kites were called "kites" in ancient times and "kites" in the north. Most people think that kites originated in China and then spread all over the world. This is a traditional folk handicraft. In fact, the earliest kites in China were made of wood. During the Spring and Autumn Period and the Warring States Period, Mo Zhai (478-392 BC), a philosopher of the Eastern Zhou Dynasty, used a wooden kite to fly to the sky in three years. Mozi was in Lushan (now Weifang, Shandong). "Cypress is a kite. It took three years to make it, but it was lost in one day." This means that Mozi finally made a wooden bird out of a board after three years of research and trial production, but it broke down after only one day's flight. This "wooden kite" made by Mozi is the earliest kite in China and the earliest kite in the world. (about 300 BC), 2400 years ago.

It was not until Cai Lun invented papermaking in the Eastern Han Dynasty that kites were made of paper, which was called "paper kites". Therefore, it can be inferred that China kites have a history of more than 2,000 years.

Mozi passed on his kite-making career to his students' open class (also called Luban). Lu Wen said that Lu Ban made kites out of bamboo according to Mo Zhai's ideal and design. Lu Ban split the bamboo, cut it into smooth slices, roasted it with fire, made it look like a magpie, and flew in the air for three days. The book "Hongshu" says: "The public transport class made a wooden kite to see Song Cheng".

At first, kites were usually used as military tools, as a means of triangulation signals, sky wind direction measurement and communication. Just like in the Spring and Autumn Period, Lu Ban made a wooden kite to see Song Cheng.

In BC 190, Chu and Han contended, and Han and Han Xin attacked Weiyang Palace to measure the distance under the tunnel with kites. In the Battle of Gaixia, Xiang Yu's army was besieged by Liu Bang's army. Han Xin sent people to make kites out of cowhide, put bamboo flutes on them, and let them work in the wind (Sean played the flute with a kite). The Han army sang Chu songs and dispersed the morale of the Chu army. This is the story of the idiom "Embattled".

There are also records about kites in the official history, which are earlier than the Five Dynasties. One is the Hou Jing Rebellion in the Southern Dynasties, when Liang Wudi was besieged by Hou Jing and the city walls were besieged. He used to fly kites for help. According to the Biography of Hou Jing in Southern History 80, in the third year of Liang Wudi (AD 549), Hou Jing made an insurrection, and the rebels besieged Liang Wudi in Jianye, Du Liang (now Nanjing), and were cut off from both inside and outside. Someone suggested making a paper crow and tying the imperial edict to it. At that time, the prince's suicide note was thrown by the northwest wind outside Taijitang for help, but it was discovered by the rebels. This is the story of Jane Wen's unfortunate failure to fly a kite for help.

According to legend, in the 5th century BC, the Greek Alkell Das invented the kite, but it was later lost. It was not until13rd century that the Italian Kyle Poirot returned to Europe from China that kites began to spread in the west.

According to other textual research, it spread to Korea in the tenth century, then to Japan, and to Europe in the thirteenth and fourteenth centuries.

There is also a story about flying kites in America. At that time, people thought that lightning and flash were the roar of religious gods and caused fear. Fran Green used kites to prove that lightning and flash are air discharges and invented the lightning rod.
