In the year 774 (21 AD) the Song-Tang Commonwealth had conquered what remained of the Tang resistance. They began to focus on what could be done about the refugees who were coming into the Eastern Border areas from Xi. At first they were allowed to settle freely. After the success of King Zhelin and the declaration of his new dynasty, the Song-Tang Commonwealth, which was only beginning to restart its trade with the Western world after the devastation of earlier wars, began putting the Xi refugees into ghettos outside of the cities. This move, which was a request of the Zhelin himself, would leave a sour taste in the mouths of the small town governments which had to force many women and children into scarcely developed and oppressively ruled slums.
