1.People’s Liberation Army ground force, from the period of Mao(1950s) to period of Hu Jintao, have gone through many times of reduction of troops and military reforms. The number of PLA has reduced from it’s climax of 5,50 million men to nowadays 1,80 million men. The strategic mission of PLA shifted from conducting the People’s warfare to winning the hi-tech local war under information conditions. The PLA ground force is the leading position in the PLA armed forces. 2.In Xi Jinpin period, the PLA ground force is still the dominant military service in PLA. There is no headquarters of ground force in PLA for a long time, the socalled 4 general departments (General Staff department, general logistics department, general politics department, general armaments department) functioned as the headquarters of the army. There are 7 military regions which commanded and controlled the army groups, navy fleets and air forces. The headquarters of military regions equaled to the headquarters of navy and air force. 3.In order to fulfill Xi’s Chinese dream as well as the strong military dream, PLA promotes the “deepen defense and military reforms”, Xi set the policy of reform: the CMC take charge the overall administration of PLA, Battle zone commands focus on combats, military services pursue their own construction. Now the 4 general departments have dissolved, then establish the headquarters of army. Furthermore the 7 military regions also had been abolished, instead of establishing 5 battle zones for the sake of commanding the joined operations. Meanwhile PLA shall cut troops number of 300,000 men. 4.In the process of the military reforms of PLA, They have abolished the original organizations based on “Great Army Discipline”, the position of PLA army declines. Now the military services are all equal. Xi Jinpin takes advantage of the reforms, by changing the military organizations to reshuffle the personal matters of higher ranking officers in PLA. Xi placed his own persons on the vital positions in order to gain the absolute control on PLA. 5.Due to political requirement, Xi Jinpin promoted the reforms urgently. It involved great changes in such few time, so some defects have merged, such as the ambiguity of authority and responsibility between headquarters of Battle zone and army service. Things would go wrong for the attached troops under such circumstances. And the opposition against reform comes from the vested interest group in army is increasing more and more. So it is hard to say how the military reform have achieved, and what the PLA ground force would shift in the future.
