The PLA was then a tough guerrilla army that lived off the land during the 1940s till about 1960s if I am not mistaken. The Chinese transformed the PLA Army, Navy & Air Force in relatively quick time, to what they are now, a modern Defense Force. We should know that the Chinese are always very quick to learn when they set their minds to it - I personally had the experience of teaching Chinese undergraduate and post graduate courses as a visiting IB lecturer in 2005 & 2006. They were all hard working, respectful and a pleasure to teach. I am sure they are the same now.
