I heard often some folks raised the doubt whether or not China could prepare enough well-trained personnel to handle various assets, be it carrier-borne aircraft, naval surface warships, etc...50% in increase is too modest. I bet double the scale at least. It's not too difficult to China's defense industry; I think the only obstacle is whether we could have enough well-trained people to handle these ships.
IMO it's a weird issue to apply on the most populous nation with so organized character...
My only question is... "Does anyone believe that China can afford to finance those additional personnel?"
If one believes it is NO, then that is the real problem but If yes, then there should be no problem!
For if China can build the hardware... then folks should set aside all the worries about the manpower! It is not like China is the kind that proceeds without meticulous planning, or there is any shortage of suitable manpower to train, just make sure the benefits are at minimum the decent ones to not drive away the applicants
As what we have witnessed at the glimpse on the J-15 pilot training, China has no real problem to prepare the needed manpower to handle its military assets... some folks simply have the groundless doubt in today's China! This is not to criticize you, I simply take the chance to address the similar notions heard often at varying threads from time to time at this forum and elsewhere somewhat ad nauseam! Hopefully we won't see any PDFer raises such groundless doubt from now on.
Btw, I intentionally put a modest increase, 50%, but in view of the actual economic and commerce needs -- must safeguard the Belt and Road projects and other overseas investments as needed -- plus the changing geopolitics situation, I believe an increase of at least 100% is a more realistic number. Let's see as time rolls on...
