Kites originated in my country. Legend has it that they were invented by Mozi. Some say that Lu Ban "carved a kite out of wood and kept it flying for three days". It is said that Han Xin flew over the enemy camp on a kite to scout the enemy and sing Chu songs to disintegrate the army's morale. This was the first time in the world that kites were used for military purposes. Franklin of the United States used kites to conduct lightning experiments. The Wright brothers invented airplanes based on the principle of kites. A display board at the American Air and Space Museum reads: "Chinese kites are the earliest human aircraft." Therefore, the emergence of kites has played an immeasurable role in the development of science and technology. The kites in Sanyuan County, Shaanxi Province were very famous in the past. And they were mainly figure kites, mainly painted with judges, Zhong Kui and the like. Therefore, some people say that it may be reasonable that Chinese kites originated in Shaanxi. Kites entered the folk around the Tang and Five Dynasties and became toys for people's entertainment and games. At the same time, it is also a good physical exercise project. During the Ming and Qing Dynasties, flying kites on Qingming Festival had become a seasonal folk activity. Kites have long been made of silk and cotton as the main masking material, and have always been a plaything for the court and dignitaries. Cao Xueqin once studied kites, wrote "Nan Yao Bei Yuan Kao Gong I", and left many kite illustrations. After Cai Lun invented papermaking, kites were introduced to the people and gradually became a toy for ordinary people to fly during spring outings. There was not much development for a long time afterwards. After the Third Plenary Session of the Eleventh Central Committee of the Communist Party of China, the spring breeze of reform and opening up blew across the motherland, and the party and the government attached great importance to the activity of kites. In 1984, Weifang City, Shandong Province, held the first Weifang International Kite Festival for the first time. In 1986, Weifang held the first National Kite Invitational Competition while holding the Third International Kite Festival. Immediately afterwards, the annual international and domestic kite festivals were held in Weifang with great fanfare, and the State Sports Commission officially included kite competitions in the national sports competitions in 1991. Subsequently, major cities across the country also competed to host kite festivals like they competed to host the Olympics. Xi'an "Zhang's kite" inherits the traditional kites of ancestors and adds mechanical devices. It relies on wind as power to make many parts of the kite move. It turns the static kite images for thousands of years into interesting moving images, forming a unique Xi'an "Zhang's kite" with distinct local characteristics. It has a great influence not only in Xi'an but also in the whole country and at home and abroad. Zhang Tianwei, the fourth-generation inheritor of "Zhang's kite", was influenced by his family to love kites since he was a child. His great-grandfather Zhang Hongsheng was a juren in the Qing Dynasty. He would make some kites for relatives and friends to play with during the Qingming Festival. Grandfather Zhang Zhaoji loved to make his own kites and had made kites such as "Bagua, Pisces, and Butterfly". His father Zhang Huanjiang was a kite celebrity in Xi'an in the 1920s and 1930s. He graduated from the "Art College" in Shanghai. He was versatile. He was not only proficient in music, art, watch repair, radio, flower planting, and fish farming, but also knitted good sweaters, especially good at making kites. In 1930, the largest Zhong Kui kite in Xi'an was made. The pillar in the middle of the kite frame was made of a whole bamboo, which was three feet high (10 meters). Five or six pieces of white hemp paper (hundreds of sheets) were used to paste this kite. The pigments were pine ink and red clay, and a broom was used instead of a brush. After the kite was made, the door in the backyard could not be exited, so everyone was mobilized to set up a ladder and lift it from the roof. The hemp rope was as thick as a thumb. Four people took turns to lift the rope, and another person carried a paste bucket to prepare for the repair of the damaged kite. Seven bows were installed on the big kite, and the buzzing sound could be heard from miles away. Sometimes, swastika-shaped firecrackers were hung under the kite, and the sound echoed from the ground to the sky. In the 1950s, neighbors called the Zhang family a "kite family". After several generations of innovation by the Zhang family, the "Zhang's kite" in Xi'an has developed into dozens of different types. Among them, the dragon kite has three to nine dynamic movements in the dragon head alone. For example, the eyes, eyelids, eyebrows, whiskers, chin, tongue, cheeks, ears and other parts can move; there are cranes, bats, and pterosaurs that can turn their necks and open their mouths to call; turtles that shake their heads and tails; centipedes, scorpions, lobsters, and mantises that are wielding their claws and teeth; overbearing crabs; moody "Zhimaguan"; the changing "Zhu Bajie carrying his wife on his back"; the funny "Charlie Chaplin", etc. The most representative ones are the "Qin Shihuang Bronze Chariot and Horses and Qin Terracotta Army Formation" kite, which displays one of the eight wonders of the world, and the "Qin Shihuang Great Wall Olympics" kite. These two dynamic kites not only reproduce the majestic posture of Qin Shihuang's unification of the world, but also further display and promote the ancient human geography of Shaanxi. They have been reported by many domestic and foreign media, newspapers, and TV stations, including the Central News Network. They have been praised by authoritative people in the kite industry as the most complex and top-level kite works. Selection of materials for Zhang's kites: (1) The skeleton of the kite is mainly made of traditional bamboo, but there are strict requirements for the selection of bamboo. It must have a growth period of three to five years, good density, good elasticity, long bamboo nodes, and thin threads or hemp. (2) The mask material is made of foreign silk, silk, and thin nylon silk, but it must be sizing treated in advance. (3) Paint pigments: Depending on the size of the kite theme, acrylic, color (alkaline dye), fluorescent color, etc. can be selected. (4) Due to the addition of mechanical transmission devices, some aluminum alloys, copper or stainless steel sheets, various metal wires, bakelite boards, etc. have been added to the material selection. (5) The adhesive currently mainly uses high-quality white latex, 502, AB glue, all-purpose glue, etc. Its basic operation process: (1) Draw a drawing in proportion according to the imagined theme, design the dynamic parts, and draw the parts diagram. (2) Split bamboo strips of different thicknesses according to the requirements of each part of the kite frame, and then heat and bend the bamboo strips of each part into the required shape on an alcohol lamp according to the drawings, and then form them into shape; at the same time, the mechanical transmission parts must be finely processed, and finally the two are combined to complete the production of the kite frame. (3) Carefully paste the silk fabric on the kite frame piece by piece. (4) Use paint to beautify it according to the type of kite (some kites are painted first and then pasted). (5) The last process is to tie the kite's lead (lifting line). Zhang Tianwei, 79 years old this year, is the inheritor of Shaanxi Province's intangible cultural heritage, the first person in China to make dynamic kites, and a first-class arts and crafts artist in Shaanxi Province. Because he was influenced by his father since he was a child, he not only loved kites, but also loved tinkering with clocks, phonographs, etc., which laid a solid foundation for the later production of Zhang's kites. Later, he worked as a technician in a factory, specializing in crafts, tooling, molds, technological innovation, and special machine design. Due to his professional habit and strong interest in kites, he combined mechanical transmission with ancient kites to make several unique "Zhang's kites". In 1986, he represented Shaanxi Province in the Weifang Kite Festival. In 2005, he made the "Qin Shi Huang Bronze Chariot and Horses and Qin Terracotta Army" kite, which is 40 meters long. In June 2010, this group of "Qin Terracotta Army" represented Shaanxi Province in the Shanghai World Expo and was exhibited in the Shaanxi Pavilion, winning unanimous praise from people from all walks of life in various countries. In 2008, he made the "Qin Shi Huang Great Wall" kite, with a 1.3-meter-tall Qin Shi Huang in front, wearing a pearl crown, a sword on his waist, his right arm raised high, and looking forward. Under the influence of wind, the "Qin Shi Huang" will shake his head left and right and wave his right arm. Behind him is the magnificent Great Wall kite, which is composed of 208 kites from six passes, including Shanhaiguan, Juyongguan, Niangziguan, Pingxingguan, Yanmenguan and Jiayuguan, 15 beacon towers, 187 battlements and a total of 208 kites. The Chinese dragon dynamic music kite made in 2009 is made up of 60 national emblems with a diameter of 60 cm, 120 national flags, 60 meters long, and took 6 months to make. This kite is the first in the country to use "sound, light and electricity" technology, and can repeatedly play the music of "Singing the Motherland" at high altitude. Before 1995, Xi'an "Zhang's Kites" were collected by many foreign friends, most of which are distributed in: the United States, Britain, France, Belgium, Germany, Hong Kong, Canada and other places. A few are collected by domestic enthusiasts, such as: Beijing, Weifang, Yantai, Yiwu, Shijiazhuang, Xi'an and other places. In 1987, the first dynamic dragon in the country with eyes that can turn left and right, jaws that open and close, and tongues that can stretch and retract was collected by Canadian friends. It was later printed on a Canadian stamp on October 1, 1999, the 50th anniversary of the founding of the country. (No pictures yet, please provide them.) (No pictures yet, please provide them.)
