and Qin era, when spearmen were used as especially highly disciplined soldiers in organized group attacks. When used in formation fighting, spearmen would line up their large rectangular or circular shields in a shieldwall manner. The Qin also employed long spears (more akin to a pike) in formations similar to Swiss pikemen in order to ward off cavalry. The Han Empire would use similar tactics as its Qin predecessors. Halberds, polearms, and dagger axes were also common weapons during this time. Spears were also common weaponry for Warring States, Qin, and Han era cavalry units. During these eras, the spear would develop into a longer lance-like weapon used for cavalry charges. There are many words in Chinese that would be classified as a spear in English. The Mao is the predecessor of the Qiang. The first bronze Mao appeared in the Shang dynasty. This weapon was less prominent on the battlefield than the ge (dagger-axe). In some archaeological examples two tiny holes or ears can be found in the blade of the spearhead near the socket, these holes were presumably used to attach tassels, much like modern day wushu spears. In the early Shang, the Mao appeared to have a relatively short shaft as well as a relatively narrow shaft as opposed to Mao in the later Shang and Western Zhou period. Some Mao from this era are heavily decorated as is evidenced by a Warring States period Mao from the Ba Shu area. In the Han dynasty the Mao and the Ji (戟 Ji can be loosely defined as a halberd) rose to prominence in the military. Interesting to note is that the amount of iron Mao-heads found exceeds the number of bronze heads. By the end of the Han dynasty (Eastern Han) the process of replacement of the iron Mao had been completed and the bronze Mao had been rendered completely obsolete. After the Han dynasty toward the Sui and Tang dynasties the Mao used by cavalry were fitted with much longer shafts, as is mentioned above. During this era, the use of the Shuo (矟) was widespread among the footmen. The Shuo can be likened to a pike or simply a long spear. After the Tang dynasty, the popularity of the Mao declined and was replaced by the Qiang (枪). The Tang dynasty divided the Qiang in four categories: "一曰漆枪， 二曰木枪， 三曰白杆枪， 四曰扑头枪。” Roughly translated the four
