What unit is Shengli Oilfield Petroleum Development Center and where is it? How is the treatment?

Belonging to an oil company, it is somewhat different from an oil production plant. Its headquarters is in the provincial building, and its working area is but not limited to Guangrao Caoqiao. For the recruited child workers, the current name is "labor dispatch workers", which belongs to the nature of labor export. The specific units assigned to the grass-roots units depend on their labor departments.
