Chinese Kites were first invented about 2,000 years ago. At about the 12th century, kites were introduced to western countries. Later, with the endless development, the different cultures of kites were slowly formed in both eastern and western countries. During the kites' development, some special local culture about kites formed after connecting with Chinese traditional culture and the skill of making kites and presenting some stories, flowers, birds, animals, and some patterns about luck on kites.
At first, kites were used in military things. In the middle of the Tang Dynasty, the society began to develop well, so kites were used in the area of entertainment instead of in military things. Besides, the material for making kites was silk at first. Later, people used paper to make kites because of the fast development of paper. When the Song Dynasty came, it had become a job to make kites. And it was during the period of the Ming Dynasty and the Qing Dynasty that the skill of making kites developed fast. At that time, people made kites and painted on the kites by themselves and then flew those kites or gave them to their relatives and friends. What's more, they thought this as an artistic activity. Recently, kites in China have been fully developed and flying kites has widely spread as a popular sport.
