Areas foreign tribal units pass through will become lost to players who had control of that area. To minimize losses, strategize on how to stop them.
With the Qiang character, not only will Qiang tribal units not appear, but they can appear in an enemy’s territory for good effect.
When public order drops, in addition to bandits, foreign tribes will appear and cause trouble. The tribes are the Wuhuan, Xianbei, Qiang, Shanyue, and Nanman tribes. Areas these tribal units pass through will become empty areas and the player will lose control of that area. Players must quickly deal with these units or lose more land.
In addition to deploying troops to deal with these tribes, another option to deal with tribes is the "character" (traits) of officers, which can prevent certain tribes from appearing in areas to begin with. If the "character" is the same as the opposing tribe, the tribe will become an ally and may appear in an enemy’s territory for good effect.
