categories are: Qi (a kind of wood) Spears, Wooden Spears, Bai Gan (A kind of wood) Spears and Pu Tou Qiang. The Qiang that were produced in the Song and Ming dynasties consisted of four major parts: Spearhead, Shaft, End Spike and Tassel. The types of Qiang that exist are many. Among the types there are cavalry Qiang that were the length of one zhang (eleven feet and nine inches or 3.58 m), Litte-Flower Spears (Xiao Hua Qiang 小花枪) that are the length of one person and their arm extended above his head, double hooked spears, single hooked spears, ringed spears and many more. There is some confusion as to how to distinguish the Qiang from the Mao, as they are obviously very similar. Some people say that a Mao is longer than a Qiang, others say that the main difference is between the stiffness of the shaft, where the Qiang would be flexible and the Mao would be stiff. Scholars seem to lean toward the latter explanation more than the former. Because of the difference in the construction of the Mao and the Qiang, the usage is also different, though there is no definitive answer as to what exactly the differences are between the Mao and the Qiang. India Spears are known as Bhala in Indian languages. Spears in the Indian society were used both in missile and non-missile form, both by cavalry and foot-soldiers. Mounted spear-fighting was practiced using with a ten-foot, ball-tipped wooden lance called a bothati, the end of which was covered in dye so that hits may be confirmed. Spears were constructed from a variety of materials such as the sang made completely of steel, and the ballam which had a bamboo shaft. The Arab presence in Sindh and the Mameluks of Delhi introduced the Middle Eastern javelin into India. The Rajputs wielded a type of spear for infantrymen which had a club integrated into the spearhead, and a pointed butt end. Other spears had forked blades, several spear-points, and numerous other innovations. One particular spear unique to India was the vita or corded lance. Used by the Maratha army, it had a rope connecting the spear with the user's wrist, allowing the weapon to be thrown and pulled back. The Vel is a type of spear or lance, originated in Southern India, primarily used by Tamils. Sikh Nihangs sometimes carry a spear even today.
