I am going to make a PPT about kites for my classmates, what is the topic?

You can take yearning for the blue sky as the title.

To yearn for the blue sky means that you yearn for the blue sky to be free, but you can't fly, only birds can, so I have to use kites instead.

Kites are a product invented by ancient Chinese laborers in the Spring and Autumn period of the Eastern Zhou Dynasty, and have been around for more than 2000 years. Legend has it that Mo Zhai made a wooden bird out of wood and developed it for three years, which is the earliest origin of kites for human beings. Later, Lu Ban used bamboo to improve the material of Mo Zhai's kite, and it was not until the Eastern Han Dynasty that Cai Lun improved the art of papermaking that kites began to be made of paper, called "paper kites".

During the North and South Dynasties, kites began to become a tool for transmitting messages; from the Sui and Tang dynasties, due to the development of the paper industry, people began to use paper to frame kites; during the Song dynasty, kite flying became a favorite outdoor activity. Zhou Mi of the Song Dynasty wrote in Old Story of Wulin: "During the Qingming Festival, people go to the countryside to fly kites and return at sunset. The word "kite" refers to kites. In the Northern Song Dynasty, Zhang Zeduan's "Riverside at Qingming Festival" and Song Su Hanchen's "Hundred Sons", there are vivid scenes of kite flying.
