Some information is available online to give a general idea of China's forces

Looked thru the information there and found some stuff that could help put together a picture of the Chinese Army
The Chinese military divides its units into two categories, Category A and Category B. Category A covers "full-training units" with complete armaments and full establishment. They have modern armaments, and undergo full-time, high-intensity military training. Category B units are "non-full-training units" which have out-of-date armaments, are under-manned, have low budgets, receive less training, often participate in productive labor, and have to have their weapons replaced and receive basic training before they can go into battle. China's Category B units are similar to the US National Guard.
As of the late 1980s the strength of the Category A units of the Chinese ground force was about 700,000, grouped into seven rapid response group armies (the 1st Army, 13th Army, 21st Army, 27th Army, 38th Army, 39th Army, and the 54th Army). Category B (Category 1 reserve) units of the Chinese ground force were in 19 group armies, 60 motorized infantry divisions, and some independent artillery divisions (or brigades).
As of the late 1980s main forces included about 35 group armies, comprising 118 infantry divisions, 13 armored divisions, 17 artillery divisions, 16 antiaircraft artillery divisions, plus 71 independent regiments and 21 independent battalions of mostly support troops (artillery, antiaircraft artillery, signal, antichemical warfare, reconnaissance, and engineer).
Regional forces consisted of 73 divisions of border defense and garrison troops plus 140 independent regiments.
As a result of the troop reductions announced in the July 1998 White Paper on National Defense, a number of PLA Divisions have been transfered to the PAP. By the late 1990s the Army had been reduced to 24-25 Group Armies incorporating a total of 90 divisions. Of these Armies, 17 are deployed in the north and northeast, positioned to repel Russia from the north, and Japan and Western powers from the east and over the Korean Peninsula.
People's Armed Police (PAP) was created in 1983 when the PLA transferred most of its internal police and border responsibilities to the new force. The PAP is still primarily composed of demobilized PLA personnel. As a result of the 1,000,000-man reduction in the PLA in the 1980s, the People's Armed Police grew by about 500,000 troops, to a total of roughly 800,000.
