In the late 1970s, the PLA began altering its promotion practices to reflect the new emphasis on professional competence. Previously, there had been no retirement system in effect, and junior and field-grade officers had remained at their posts for many years with little opportunity for advancement. When promotion occurred, it was based on seniority, political rectitude, or a patron-client relationship. Officers advanced up a single chain of command, remaining in the same branch or service for life. In 1978 the PLA reinstituted the retirement system established by the 1955 Military Service Law and promulgated officer service regulations, which set retirement ages for military officers. Thus the PLA began a two-pronged effort to retire older officers and to promote younger, better educated, professionally competent officers. Older officers, including many over seventy years of age, were offered generous retirement packages as inducements to retire. The PLA also formulated new promotion standards that set minimum education levels for officers and emphasized education in military academies as a criterion for promotion. Officers below the age of forty had to acquire a secondary-school education by 1990 or face demotion. Furthermore, past promotion practices were to be discarded in favor of greater emphasis on formal training, higher education levels, and selection of more officers from technical and noncombat units. With the reduction in force begun in 1985, professional competence, education, and age became criteria for demobilization as well as promotion. By 1987 the PLA's promotion practices were based more on merit than they had been a decade earlier nevertheless, political rectitude and guanxi (personal connections) continued to play an important role in promotion, and no centralized personnel system had been established.
