Kites were invented by ancient working people in the Eastern Zhou Dynasty and the Spring and Autumn Period in China, and have been used for more than two thousand years. According to legend, Mo Zhai made wooden birds out of wood, which took three years to develop, and was the earliest origin of human kites. Later, Lu Ban used bamboo to improve kite materials in Mo Zhai. It was not until Cai Lun improved papermaking in the Eastern Han Dynasty that people began to make kites out of paper, which was called "paper kites".

? In the Northern and Southern Dynasties, kites began to be a tool for transmitting information. Since Sui and Tang Dynasties, due to the development of paper industry, people began to use paper to paste kites. Flying kites became a popular outdoor activity in the Song Dynasty. In Song Dynasty, Zhou Mi wrote in Old Wulin: "During the Qingming Festival, people fly kites in the suburbs and return at dusk." Kite "means kite. There are vivid kite-flying scenes in Zhang Zeduan's The Riverside Scene at Qingming Festival in the Northern Song Dynasty and Su Hanchen's The Hundred Poems in the Song Dynasty.

In recent years, some hospitals and sanatoriums at home and abroad have adopted "kite therapy" to treat children's mental depression, neurasthenia and mental retardation, and have also received magical results. Flying a kite is also a brain-strengthening exercise, which requires all your heart and soul. Only by properly handling the relationship between flying kites and wind direction and wind speed, we have to let the kite-flying people use their brains: the necessary condition for flying kites is that there is wind on the ground, but it is not easy to fly if the wind speed is too high, because the horizontal force of the air is too great at this time, it is difficult to "lift" and control the kite; Flying kites is most afraid of uncertain wind direction, because kites are most likely to be planted at this time. The ancients thought that the higher realm of flying kites was that when flying, the first line was connected. When it's not flying, it's like a horse lying in a trough. After flying, it's like entering a racecourse. You should be full of energy, pull the line tightly as a reins, like a horse, and then look at the sky and run back and forth with the drift.

When flying, the brain is highly concentrated, which will undoubtedly eliminate people's inner distractions; People who can fly will look at the blue sky and feel open-minded; In addition, in spring, the grass grows and the warbler flies, which is a beautiful dialogue between man and nature.

However, the wind in spring is neither too mild nor too small, and the weather is neither too cold nor too hot, so flying kites in spring is the best. When flying a kite, try not to choose cloudy or rainy days, because too dim light and concentrated vision will lead to myopia.
