Like the rancher using the lasso to catch cattle, the lasso used on the battlefield was employed to catch the enemy alive. In the chuanci short stories, the mysterious sia Ciuran Ke taught Li Jing how to use the lasso. When Li Jing became a General of the Tang, he trained a squad of selected warriors in the skill of using the lasso called feisuo. The length of the feisuo is from 3.5 meters to the maximum of about 10 meters; and the best material to make the feisuo lasso out of is a combination of threaded cattle tendon, threaded dear tendon, human hair and silk. The noose of the feisuo lasso is attached with hooks. When the battle starts, the trained feisuo warriors mixed with ordinary soldiers, and then they gathered when the leader of the enemy was spotted. They threw the rope to capture the leader alive. Once the leader was captured, the enemy troops would scatter in a short period of time.

       The cavalry in the Yuan, Mongolian, dynasty were good in using the lasso. They made the running knots so they could fasten the knot circling the neck of the captive. In the Ming Dynasty, the lasso was combined with jhua, the mace; the mace was fastened with the rope on one end and could be thrown to hit the enemy. However this device could not always bring the weapon back in time, so it was only used in special situations.

       In ancient chuanci stories and wusia novels, this weapon, which can capture the enemy alive, is commonly used. The throwing skill of using this weapon is also described in using other weapons especially the various kinds of darts.

       In Yinma Liuhuahe by Siao Yi, a unique weapon called shenyin tiejhua, literally meaning the claw of the divine hawk. The five claws made of steel are finely designed; the user only needs to shake the body of this weapon, which is made of a series of knots, and the claws will grab the object firmly and immediately.
