Unfortunately that doesn't factor in the differences between advancements in training, education and exercises between the Chinese Navy's past and present.
If you really think the competency of an officer of XYZ age in the Chinese Navy in the late 1980s was the same as an officer of the same XYZ age in the Chinese Navy of today then I'd like what you're smoking.
Please, there's a difference between saying someone is "young" in the context of the historical age of commanders for ships in a Navy, versus saying someone is young and therefore unfit for the commanding officer position.
And also I'd like if if you don't put words in my mouth. What I said was that officers in the modern Chinese Navy who may be younger than officers in the Chinese Navy of twenty or thirty years ago are likely just as competent if not more competent due to differences in education, training and exercises.
Competency and experience is not only a reflection of age, but also a reflection of the quality of education, quality of training and quality of exercises. I would bet a limb that the competency of the Chinese Navy's officers today compared to what they were able to turn out two or three decades ago are far superior.

though this is all a bit academic -- I watched the video A man was talking about, I didn't see an officer with a rank of Commander or Captain aboard the DDG who was the Commanding Officer. The highest ranked officer I saw was a Lieutenant.
