The People's Liberation Army (PLA) has not always used ranks or insignia. In common with the practice of the Red Army at the time of its founding in 1927, neither were used until 1955 when a system of ranks was established. As a result of the Cultural Revolution, ranks were abolished in May 1965 (this led to a similar reform in Albania in the midst of the Albanian Cultural and Ideological Revolution). After the Sino-Vietnamese War of 1979, reforms in the PLA began to be made to professionalize the armed forces once more. The 1984 Military Service Law provided for the resumption of rank, but disagreements on what ranks were to be used and who would receive them caused the revival of rank to be delayed until 1988. The following ranks and their respective insignia shown are those used by the People's Liberation Army Ground Force. Current ranking system PLAGF officers The current system of officer ranks and insignia, a revision of the ranks and insignia established in 1955, began usage in 1988. The 1955 to 1965 marshal officer ranks of yuánshuài (5-star Marshal) and dà yuánshuài (6-star grand marshal) were not revived. The general officer ranks (jiang) were revised by the addition of semi-circular wreath at the bottom of the insignia and by a change in the name of the highest general officer rank from da jiang (4-star General) to yi ji shang jiang (4-star first class colonel general). This highest rank in the new system was never held and was abolished in 1994. The field officer (Xiao) and company officer (Wei) ranks were the same in title and insignia except that highest company-level officer rank of Da Wei in the 1955 to 1965 system was not included in the revived ranks. The final difference between the two systems is that in 1955 to 1965 there existed a warrant officer rank, Zhun Wei, which was not incorporated in the revived rank system, while new system had a rank for officer cadets, Xue Yuan. Despite being the rank below Shao Wei in both systems, the insignia have no similarities. Officer rank names are usually not translated literally, but rather to a corresponding rank system. This can lead to different translations being used depending on the system chosen for the correspondences. The 1955–1965 system, with its greater number of officer ranks, is usually translated using the Soviet rank system of that
