In all seriousness, the incompetence and backwardness highlighted here is deeply concerning. China's modernization of its armed forces isn't a vanity project, it is of the utmost importance to national security. It is an existential matter. What happened to Russia in Ukraine must not happen to China.
The PLAGF/PAP is tasked with adopting modern, "informationized", "intelligentized", network and system-centric warfare; this is very complicated stuff. The Chinese leadership and people must have confidence in their military. The Yakety Sax images shown here undermine that confidence and that cannot be acceptable.
Step up.
A lot of the people who actually join as grunts are young and not extremely high educated. For many, it might be their first job.
"a lack of professionalism in other militaries does not excuse ones in PAP"
Arguably yes it does. Does China actually need a baseline professionalism higher than say France or US? Not necessarily, because these guys are not going to be impacted that much by their lack of professionalism in a war.
I don't know what you mean about Russia, aren't they the ones that care a lot about their image, always show "correct" and "manly" behavior from their troops, unlike the above examples from China, US et al?
Thats actually an excellent example of you can look or be as supposedly professional with your ground forces as you want, fat lot of good it does once their contracts expire and most of them just go home leaving gaps in your lines. To avoid facing Russia's issues, China just needs to have motivations to fight and a clear contract structure.
In a war, the above guy will, in his current state at the very tops be acting as a guard in occupied territory. He will unlikely even see anything but potential small arms. Now from his unit, maybe 1/4 of the most ambitious to stay long term in the military and continue their education will prove themselves and join a frontline unit. This is the same as with any army, a lot of the low level ones aren't necessarily passionate or skilled in what they do.
