For an entire month, Jiang Yuan mainly focused on Qinghe City, striking out in all directions to solve cases.
The Qinghe City Bureau's designated "Year of Assault on Accumulated Homicide Cases" seemed to have turned into "Jiang Yuan's Year of Assault on Accumulated Cases", but that was essentially the goal of the Qinghe City Bureau. Such a grand combine harvester should not merely work the fields of Ningtai County; that would indeed be unreasonable.
As for the costs of working in other districts and counties, including Qinghe City Bureau, obviously none could afford them—the cost of living index shot up with the needs of big cities. Small cities couldn't afford the executive cars of Didi, much less afford Jiang Yuan. However, Qinghe City Bureau was able to offer a good deal of administrative perks.
