《将苑·卷二·西戎》
他们住在大漠以西，种族繁衍很快，有广阔、险峻的形势，他们习惯于逞强行凶，不愿臣服于中原，所以只有等待时机，当他们外遇他族挑战，内朋混乱时，才可以向他们进兵，彻底地击败他们。
自碛石以西，诸戎种繁，地广形险，俗负强很，故人多不臣。当候之以外衅，伺之以内乱，则可破矣。
They live in the west of the desert, and their races multiply quickly. They have a vast and dangerous situation. They are used to acting aggressively and refuse to submit to the Central Plains. Therefore, they can only wait for the opportunity. When they encounter challenges from other tribes and chaos within the tribe, they can send troops to defeat them thoroughly.
