Describe spears and shields and talk about their functions.

The structure of a spear is very simple, with only two parts: the head and the handle. The spearhead is divided into "body" and "epiphysis". The middle part of the spear body is a "ridge", and the left and right sides of the ridge expand outward into blade-like spear leaves, which gather forward to form a sharp point. The "skeleton" is a straight tube used to connect the spine, with a thick bottom and a thin top, which is convenient for handling.

Spear is a kind of cold weapon, similar to pike and longer than pike. In the true sense, spears are generally 5~6 meters long, which are mainly used by infantry.

The main function of spear is to stab, which consists of the impact of the spear head, handle and handle end. It ranks with Ge, Ji, Shu, Gong and Ya as the "Five Soldiers".

Early shields were made of wood, leather and other materials, painted on the surface, rectangular or trapezoidal in shape, and generally less than three feet in length. It is divided into infantry step shield and chariot sub-shield (small shield).

In the Spring and Autumn Period (even the Warring States Period), the shield was still made of wood and leather, but its shape changed greatly. Most of its upper part is made into a symmetrical double arc, and its surface is painted with exquisite patterns. The height of the shield is generally more than 60 cm and the width is about 45 cm.

A shield is a broad piece of armor (made of metal, wood or leather, for example), worn on the arm or held by the hand. In the past, it was generally used to protect the body (such as spears, arrows or swords) on the battlefield or in single-person combat.

Extended data:

Spear is one of the cold weapons with a large number of equipment and the longest use time in the ancient army. Spear has a long history, and its most primitive form is a wooden stick with a sharpened front end, which is used for hunting. Later, people gradually learned to make spears from stones and animal bones and tie them to the front end of a long wooden handle to enhance the killing efficiency.

Shield, which the ancients called "dry", was a tool of war with Ge in ancient times. Later it was called "Pai" and "Peng Pai". Legend has it that the earliest shield in China existed as early as the Yellow Emperor. There is a myth about the hero "Xing Tian" in Shan Hai Jing, which describes his heroic gesture of holding an axe with one hand.
