When paper was invented. It replaced bamboo to make a lighter fengzheng, which was named paper bird at that time. According to historical records, emperor Liangwu of the Northern and Southern Dynasties (420-589 AD), used a Fengzheng to send his message for help when he was besieged in a city. In the Song Dynasty (960-1270 AD), people loaded gunpowder on Fengzheng. To assault the enemy is by tying a piece of kindling insence on the fuse and flying it into the sky above the enemy camp, where it exploded and caused chaos. Then they took the advantage to launch an attack and defeat the enemy. It is thus evident that Fengzheng was originally made for military use.
造紙術(shù)的發(fā)明，使制作風(fēng)箏的竹料進(jìn)化成了紙質(zhì)，這種新發(fā)明更輕的風(fēng)箏在當(dāng)時(shí)被叫做“紙鳶”。據(jù)史書(shū)記載，在南北朝，梁武帝被侯景圍困于臺(tái)城就是通過(guò)風(fēng)箏把救援信送出城外。 在宋朝（公元90-1270年），人們往風(fēng)箏上加上火藥， 他們是這樣用風(fēng)箏進(jìn)攻敵人的: 在風(fēng)箏尾端不過(guò)綁上引火線，然后把風(fēng)箏放飛到敵人的營(yíng)地，這樣爆炸后就會(huì)引起敵人營(yíng)地的騷亂。 隨后他們搶盡先機(jī)，發(fā)動(dòng)進(jìn)攻，打敗敵人。由此可以證明，最早的風(fēng)箏是用在軍事上的。
