The full name of the "Petroleum Second Franchise" is "Petroleum Company Second Department Family Campus". It was the workers and family members, who were the ones living on the campus.
Originally, this place belonged to the company. But, after the Millennium reform, the ownership was returned to the place. So, when the apartment murder occurred later, the place belonged to the jurisdiction of the Moyang branch. Therefore, all cases at that time were handled by the key case investigation unit of the Moyang branch.
Now, after 10 years, there has been little change in the family campus of the factory, as it is still retaining the old buildings from the 80s and 90s of the last century. Because the campus was originally designed for the workers, the largest surface area here is only just over 80 square meters.
