Kites were called "kites" in ancient times and "kites" in the north. Most people think that kites originated in China and then spread all over the world. In fact, the earliest kites in China were made of wood. During the Spring and Autumn Period and the Warring States Period, Mo Zhai (478-392 BC), a philosopher of the Eastern Zhou Dynasty, spent three years making a wooden bird, but it broke after only one day's flight. This is the earliest kite made by Mozi in China and even in the world. (about 300 BC), 2400 years ago.
It was not until Cai Lun invented papermaking in the Eastern Han Dynasty that kites were made of paper and were called "paper kites". Therefore, it can be inferred that kites have been in China for more than two thousand years.
