Based on a rough estimate, the Jingnan Army in Jin land numbered around 150,000. This figure didn't include the Jin auxiliary troops attached to them. Strictly speaking, Zheng Fan's troops weren't part of the Jingnan Army's regular forces; since he commanded many Jin soldiers, his forces were more akin to "auxiliary troops."
Originally, everyone assumed that if Lord Jingnan came, he would bring at least 70,000 to 80,000 Jingnan troops. This force was intended not only to compensate for the losses of the Yan Army's Left Army of the Eastern Conquest Army but also to surpass the pre-war troop quality and combat effectiveness of the Eastern Conquest Army.
