The Barbarian Tribe's migration into North City, if they were directly moved to places where the common folk of Great Sum congregate, could easily lead to conflicts between the Barbarian Tribe and the people of Great Sum.
But if there is no interaction between the two groups at all, it would be unlikely for the Barbarian Tribe to fully assimilate into Great Sum culture.
Therefore, Lu Chen offered a compromise by setting up counties specifically for the Barbarian Tribe to reside in North City. Of course, each household had to be registered and strictly controlled; however, as long as they were granted permission, they could also enter cities inhabited by the Great Sum people.
The most important point was that the relatives of the captured Barbarian Tribe members could directly visit them. This made the recently migrated Barbarian women in North City very happy.
