They ARE labeled, but they don't exactly come back down in a controlled fashion where the labels necessarily survive.
And even if it the label survived, its not like a bunch of part numbers would mean anything at all to a lay person and would still generate these dumb posts.

If you zoom in on some of the pictures you can see what looks like partial labels, maybe part or serial numbers? But all of them are pretty burned and chewed up. And based on the barnacles, it spent a lot of time at sea too before washing up.
That's pretty typical. SpaceX debris that washes up in the Caribbean is in similar condition.

That is absolutely the PS3 stage of an Indian Polar Satellite Launch Vehicle. It is a very unique upper stage in that that 'tank' is actually a Kevlar wrap over a solid Hydroxyl-terminated polybutadiene (HTPB) propellant. The part that is broken on the bottom is where the nozzle sat; they use a 'submerged' nozzle where much of the nozzle core is actually up inside that.
So, it is not a vessel for a liquid propellant like many people would think.

Eh, yes they do? They have 2-3 satellites they launched themselves way back in 2015 or so.
My point was that a Chinese weather balloon caused diplomatic reactions still not rolled back today and a military operation to shoot it down, and when China launches a rocket it is alway doom and gloom about its path and the debris. You know very well how MSM scream when something is Chinese.

No, a Chinese airborne reconnaissance platform - in the press quickly dubbed 'spy balloon' - caused diplomatic reactions, as well it should. The problems would have been averted had the USA authorities reacted when the thing entered their airspace instead of when it was about to leave it - surely China would not object to having their 'blown off-course weather balloon' taken down before it could crash on a school bus full of children? - but that is another story.
China does have a problem with spent stages from its rockets falling down on land but the victims mostly reside in China itself due to the location of the launch bases and the launch trajectories, e.g.
China's rocket dropping habit, Chinese rockets are frequently launched over populated areas - sometimes crashing into towns and villages. This video looks at why China began doing this in the first place and how developing reusable rockets might fix this issue.
