Hi Haodong,
Maybe wikipedia is not available in your country, so I had a quick look for you.

Here’s what I found under ‘History’:
Kites were used approximately 2,800 years ago in China, where materials ideal for kite building were readily available: silk fabric for sail material, fine, high-tensile-strength silk for flying line, and resilient bamboo for a strong, lightweight framework. Alternatively, the kite authors Clive Hart and Tal Streeter hold that leaf kites existed far before that time in what is now Indonesia, based on their interpretation of cave paintings on Muna Island off Sulawesi. The kite was said to be the invention of the famous 5th century BC Chinese philosophers Mozi and Lu Ban. By at least 549 AD paper kites were being flown, as it was recorded in that year a paper kite was used as a message for a rescue mission. Ancient and medieval Chinese sources list other uses of kites for measuring distances, testing the wind, lifting men, signaling, and communication for military operations. The earliest known Chinese kites were flat (not bowed) and often rectangular. Later, tailless kites incorporated a stabilizing bowline. Kites were decorated with mythological motifs and legendary figures; some were fitted with strings and whistles to make musical sounds while flying.
One ancient design, the fighter kite, became popular throughout Asia. Most variations, including the fighter kites of India, Thailand and Japan, are small, flat, rough, diamond-shaped kites made of paper, with a tapered bamboo spine and a balanced bow. Although the rules of kite fighting varied from culture to culture, the basic strategy was to maneuver the swift kite in such a way as to cut the opponent’s flying line.

In Europe unambiguous drawings of kites first appeared in print in the Netherlands and England in the 17th century, pennon-type kites that evolved from military banners dating back to Roman times and earlier were flown during the Middle Ages. Joseph Needham says that the earliest European description of a kite comes from the Magia Naturalis written in 1589 by the Italian polymath Giambattista della Porta (1535–1615).
Hang gliders are based on the Rogallo wing, originally marketed as a mylar self-inflating kite named the Flexikite.
In 1750, Benjamin Franklin published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. Benjamin Franklin wisely never performed his experiment, but on May 10, 1752, Thomas-François Dalibard of France conducted Franklin’s experiment (using a 40-foot (12 m)-tall iron rod instead of a kite) and extracted electrical sparks from a cloud.
The period from 1860 to about 1910 became the “golden age of kiting”. Kites started to be used for scientific purposes, especially in meteorology, aeronautics, wireless communications and photography; reliable manned kites were developed as well as power kites. Invention of powered airplane diminished interest in kites.World War II saw a limited use of kites for military purposes (see Focke Achgelis Fa 330 for example). Since then they are used mainly for recreation.
