I can understand that, their public affairs office still in the stage of "displaying the martial side" of the military, not like the US who has displayed way enough on CNN, and now can do something about the "human side" of the military...China has not go to war for almost 3 decades now, the last was the border skirmish with Vietnam and most of those who fought there were retired by now, and that ain't fit the modern warfare that PLA shifting gear to either; fighting insurgencies was handled by the People's Armed Police but those, even with suspected foreign help including the US, usually just small cells with unsophisticated weapons and tactics, not enough to be marked at the same level of sophistication as the Taliban or Al-Qaeda.
Think about this, the largest deployments of PLA in the last 20 years were during natural disasters - annual massive floodings at various rivers, and the 2008 earthquake top it all...national day parade doesn't count on my book, that's a display, a show, not actual operations.
