Are these wins defined within the framework of being good for China, investing in its future progress and success? or for global perception?
Because some are clearly better for perception e.g. Chinese export 4.5 gen older fighter shooting down multiple latest western 4.5 gen fighters and some 4th gen fighters. This while great for perception of Chinese capabilities isn't great for allowing China to continuing its relative stealthy ascend. It's better to be underestimated.
China is revealing how far ahead it is. It's not revealing it intentionally most of the time but it's too hard to hide and the China haters are more motivated by hate and insecurity so they interpret obvious signals of China being so far ahead with the delusion that it's China bots promoting it when it's usually just regular people or China defenders saying those things and promoting those truths.
E.g. China isn't the one promoting how much its car exports are rising and how great their cars are. It's often their competitors doing that and media.
China
hid most of the latest military developments during September parade, toning down just how far ahead it is. There are many goodies that would show how many times the US is being lapped militarily by China if it revealed some more secretive strategic weapons. While it's also an occasion for internal celebration, the intention there was not to promote some military superiority over the US even though

we know.
