Bow and arrow is a powerful long-range weapon. Bow consists of elastic bow arm and flexible bow string; Arrows include arrows, shafts and feathers. The material of the arrow is copper or iron (modern arrows are mostly alloy), the handle of the arrow is bamboo or wood (modern arrows are mostly pure carbon or aluminum alloy), and the feathers are carved, eagle or goose feathers. It is one of the important weapons used by the army and hunters.
Engels said in 1863: "Bow, string and arrow are already very complicated tools, and it takes long-term accumulated experience and developed intelligence to invent these tools." The invention of bow and arrow may be related to the origin of music. Bernard, a British historian of science and technology, once said: "The rough sound made by bowstring may be the origin of stringed instruments. Therefore, bows contribute to the scientific aspect of music and the artistic aspect of music. " The ancients in China had a unique theory, that is, "a bullet comes from a bow" (Biography of Gou Jian's Conspiracy in the Spring and Autumn Period of Wu Yue). Finger flick slingshot. In Oracle Bone Inscriptions, the letter "B" is written as a bow, and there is a small bag in the middle of the string to hold the projectile. Slingshot of this shape has always been very popular in China. Some jugglers in modern Beijing Tianqiao use this slingshot. Perhaps, our ancestors first invented only a slingshot used to launch pebbles or mud balls, and then further explored it before using bows to shoot arrows, thus producing bows and arrows.
