It can be said that in Liu Xie's view, using such rootless barbarians like the Southern Huns is much more reassuring to him than employing the Han generals of the Central Plains.
However, in Sima Yi's perspective, this fundamentally isolates oneself from the world. Bringing the Southern Huns southward has never been a problem for the Han Dynasty, as the Southern Huns have always been submissive under the Han Dynasty, and serving as an auxiliary army posed no issue.
The problem lies in Liu Xie's lack of control over the power of the Southern Huns. Liu Xie's method of bringing the Southern Huns south is completely different from Yuan Shao's approach of bringing the Northern Hu people southward back then.
