In fact, at the beginning of the reform and opening up, because most state-owned enterprises had redundant personnel, they rashly laid off employees, which brought trouble to the country. At that time, in order to improve the efficiency of employing people within the system and revitalize human resources, the state encouraged state-owned enterprises to take out surplus personnel to engage in the tertiary industry.
