The Aud army prisoners leaving the Lipei POW camp, although a small number did indeed leave Lipei territory directly, the vast majority returned to the Aud army camp.
Faced with the chief's skepticism, many cited the weak guard of the Lipei army as the reason for escaping.
Of course, lies cannot cover the truth. Soon someone spoke the truth, and for a time the Aud army was greatly shocked by the generosity of the Lipei army.
To suppress this kind of rumor from spreading, the Aud army high command deceived themselves by asserting that these escaped Aud prisoners had collectively escaped, rather than being deliberately let go by the Lipei people.
However, they dared not reuse these prisoners, as who knows if someone might switch sides. So most of them were sent to the rear, no longer allowed on the front lines.
