When it comes to kites, you have to clear your name first. Kites are commonly known as southern paper kites and northern paper kites. Cao Xueqin's monographs on kite technology are called "Kite Flying Test in the South" and "Kite Flying Test in the North". The word "kite" appeared in Tang poetry, but this kite refers to the iron horse under the eaves, which can't be counted from ancient times to today. Then there are different opinions about the origin of kites. One is the theory of wooden kite reconnaissance. One is game toys ... but some people question why we fly kites in Tomb-Sweeping Day instead of Mid-Autumn Festival. This leads to the third statement; Grave-sweeping ancestor worship said. Tomb-Sweeping Day sweeps graves and burns paper money. At first, it didn't burn paper. The ancients swept the grave, tied paper money to the top of a long bamboo pole and inserted it in the grave. The early spring breeze is powerful, and paper flowers are flying, symbolizing the spirit of ancestors forever. From flying paper on the grave to flying kites on Qingming Festival.
Flying kites originated from ancestor worship and can also be found in ancient poems. Bai Juyi, a poet in the Tang Dynasty, wrote the poem "Cold Food and Wild Hope": "Crows make trees faint, and those who eat cold food on Qingming Day cry. The wind blows the paper money in the wilderness, and the spring grass in the tomb is green. Pear blossoms reflect poplar trees, full of parting places. In the dark, Chunzhong cried but didn't smell it, and Xiaoxiaoyu returned. " There is a poem in the Seven Laws of the Song Dynasty: "There are many tomb fields in the north and south hills, and the Qingming is different." Paper becomes a white butterfly, and tears become a red cuckoo. When the sun goes down, the fox sleeps in front of the grave, and the children smile at the lights when the night returns. If there is wine in life, there must be drunkenness. Not a drop reached Jiuquan. "In Bai Juyi's poems, the wind blows paper money in the wilderness, and in Song poetry, the paper turns into white butterflies, all of which are disproof. White butterflies swaying in the wind when the paper is not gray must be more beautiful. Secondly, Shen Congwen, a master of modern literature in China, has a short story Jing, which describes the custom of tying paper to sweep graves in Xiangxi, which is the best evidence that Tomb-Sweeping Day flies kites and worships ancestors.
