The contemporary imperial army is divided into the Six Armies of the Northern Government and the Sixteen Guards of the Southern Government, the former garrisoned in the palace city as the Emperor's personal guards, and the latter stationed in the metropolitan city under the chancellor's jurisdiction. Comparatively, the Six Armies of the Northern Government are elite troops, composed primarily of sons of nobles, outstanding members of the Sixteen Guards, and disciples from renowned sects. Among them, the Zuo Long Army is one of the Six Armies of the Northern Government, a mounted unit known as the leading vanguard of the Tang Dynasty.
