Since the first Gulf War in 1991 to the second Gulf War in 2003, several regional conflicts already proved again and again that high-tech and information warfare is not only a contest between two military rivals but also a competition of mentality and morale. At present, the mainland China has already taken psychological operation as an important foundation of winning a information war and psychological training, that is a key link of psychological operation. Therefore, the mainland China develops psychological training actively, and devotes to strengthening mental quality of the officers and soldiers to improve effectiveness of the military theories. Through the study the present situation of China People's Liberation Army' psychological training, development we find that it has achieved a great deal. Our military should adopt the thinking patterns of ”learning from the enemies” and ”seeing the enemies as enemies” and focus on the mental quality training of our own military and strengthen officers and soldiers' pressure resistance during a war.
