Source of weapons:

From the Shang Dynasty to the early Warring States, the arrows of nomadic people in the Central Plains and surrounding areas were mostly two-winged arrows, and some were barbed. Two-wing cymbals are divided into solid round neck (sound: hard) type and hollow cymbals (sound: poor) type (or hollow cymbals). Solid collar type is to insert the arrow into the hollow shaft and fix it; Hollow pin type is to insert the arrow shaft directly into the hole at the tail of the arrow and fix it.

The solid round neck type is commonly used in the Central Plains, and the hollow collar type is used by nomadic people. During this period of war, dysprosium was cast differently in different countries, and its penetrating power was stronger than before. The development of biplane reached its peak.

Three-winged cymbals appeared at the end of the spring and autumn period, which are also divided into round neck and cymbals. A three-wing trowel is a trowel with three wings on its head, and its cross section is an inward concave triangle. At the end of the Warring States period, Qin began to equip the army with a large number of triangular arrows. The triangular arrows unearthed from the terracotta warriors and horses pit of Qin Shihuang have the highest scientific and technological content, and the length, radian, angle and weight of the arrows are almost the same, and they are as sharp as new.
