Ji (polearm)

The ji is a specialized Chinese polearm used for many centuries. A polearm is a long-reaching weapon held with two hands. Many people translate the word ji as a spear or a halberd. However, these English terms are conceptually different from the actual ji. This weapon was used for over 3,000 years in China. Its history stretches from the early Zhou dynasty to the end of the Qing dynasty. Today, the ji remains relevant through training in many Chinese martial arts.

The mechanism of the ji makes it a highly versatile tool. It was originally a hybrid of a spear and a dagger-axe. The weapon features a sharp spear tip at the very end of the shaft. Most versions also include side blades attached to the pole. There are often empty spaces between the shaft and these blades. A wielder could use the spear tip to strike directly. They could also use the side blades to hook an opponent by pulling the weapon back. Some fighters even used the flat side of the blade to slap an opponent. This technique could knock a rider off a horse. Many jis also featured a rear counterweight for striking.

There are several distinct types of ji based on their blade configuration. One variety is called the qinglong ji, which translates to "green dragon ji." This version has a spear tip with a crescent blade on only one side. Another common type is the fangtian ji, or "sky-piercing ji." This version is more symmetrical because it has crescent blades on both sides. During the Song dynasty, several other weapons were called ji. However, those later weapons actually developed from spears rather than the ancient ji design.

Archaeological finds provide a clear look at the history of this weapon. We see evidence of the ji in many different historical contexts. In the Eastern Han dynasty, bronze figurines show cavalry using the ji. These figures also show the weapon being used by charioteers.

We also find many examples in the tombs of the Ming dynasty. For instance, the tomb of Prince Zhu Tan contains several pottery figurines. These figures show people carrying jis in formal processions. Some of these figurines even show a ji being carried alongside a large axe.

Legends often blur the line between history and storytelling regarding the ji. The famous novel *Romance of the Three Kingdoms* features a warrior named Lü Bu. He is often associated with a specific polearm called the fangtian huaji. It is currently unknown if this specific weapon was a real historical object. The author, Luo Guanzhong, may have used it as a literary device. This is similar to how the *yanyuedao* is linked to the historical figure Guan Yu. Because of these stories, some weapons are named in honor of legendary characters.

Scientific study of the weapon relies on physical records and illustrations. The first historical or archaeological evidence for this specific polearm appears in a military manual. This manual is called the *Wujing Zongyao*. It contains illustrations from the 11th century during the Song dynasty. These documents help historians understand how the weapon's design changed over time. By studying these manuals, we can trace the transition from the ancient hybrid weapon to the spear-based versions used later. This allows us to distinguish between the original ji and later similar tools.

The ji represents a complex system of combat technology. It combines the piercing ability of a spear with the hooking and slashing power of an axe. This combination allowed infantry, cavalry, and charioteers to adapt to different combat needs. The weapon's long history shows how much importance was placed on versatile tools. It connects the ancient bronze-age traditions of the Zhou dynasty to the later imperial eras of China. Understanding the ji helps us understand the evolution of military technology in East Asia.
