That statement is kind of stupid and quasi-racist(and I don't play the race card) as the American themselves were amateurs in 1941 compared to the best carrier force in the world -Japan's Kido Butai carrier strike groups that struck Pearl Harbour and ravaged the Pacific and Indian Ocean for nearly 2 years.For instance a 180 to 250 plane strike package from 4 Japanese carriers would only take 15-20 minutes once airborne to assemble and organize toward a target,only after Midway did the USN get this sort of proficiency-and the prewar racist opinions of the Japanese fliers etc were similar to the now opinions of the PLAN CBG/fliers.I hope that it doesn't take a war to prove them wrong.Discipline,proficiency,organization,cool-headed logical assessment decision making is NOT exclusive to just anyone.BTW a lightning quick take-over of TW with minimum loss on both Chinese sides -hermetically sealing TW island and daring US,Japan to cross this redline will put China on the map and erase the Japanese 1895 victory will put paid to the Century of Humiliation-unlike this grinding debacle in Ukraine which has destroyed any goodwill and respect for the Russian Arm forces.

Seeing Chinese naval aviation pilots put such effort and professionalism into their craft, despite the fact that they're far from the hypothetical first line defense in ww3, really shows how the core of the PLA organizational values have been properly transferred into new branches.

PLA has for most of its existence lived with the fact that their equipment may not be the best, but that a shortfall in equipment can be made up for by the quality of the individual solider and the organizational effectiveness of the unit.

Communist China stood behind the creation of some of the most elite forces in terms of training, initiative and morale in the latter half of the 1900s, such as the 8th route army, the PVA, the Viet Cong and PLA as a whole itself. They did not need overwhelming artillery, air or tanks to efficiently defeat enemies.

Translating these values into naval aviation is much much easier said than done, but from what I can see, PLA has really prioritized the training of the personnel rather than just mindlessly acquiring more tech + platforms and then hoping that they will just crush opponents with sheer force.

"Why is the wake of Shandong CV-17 so much smaller than the other vessels nearby? They are in a convoy so assumed the speed is the same? Maybe some prospective optical illusion?"

Different hull design can cause different wakes. Beside the overall hull design, CV-17 has a big bulbous bow.

Engineering Analysis of Wake​

A wake is created because boats must push their way through water. Because every action has an equal and opposite action, bow waves emanate out from where a boat passes through the water. These waves propagate at an angle of about 19 degrees from the boat. As boats move through water, they build up bow pressure (in front of the boat) which actually pushes the water aside, rather than the boat physically parting the water. One method of improving efficiency and minimizing wake is to design the hull such that the bow pressure front is as far out ahead of the bow as possible. This can be achieved by placing a rounded projection in front of the bow, and increases efficiency by up to 25% at designed speed. Another method is to split the hull into several sections, and design the hulls such that the inner wake is canceled out. This is the idea behind a catamaran.

No, the ships of a carrier group don't sail so close together during operations, they just came together for a photo. So it is quite possible that the speeds are very different and that the escort ships soon operated far away from the aircraft carrier again.

There is another, simpler reason: the CV-17 hull is significantly longer than the other ships. Longer hulls suffer less hull resistance at same speeds and consequently generate relatively less waves. On shorter ships the stern will start digging into water at lower speeds which creates a large wake.
