I see, it is the proposal from 8th. It is sort of a CZ-8 competitor. I have no more information than you do.

Personally I wish this project does not go beyond the brochure. It is a duplication of CZ-8 class and wast of money. The only technical reason that 8th institute was tasked to make CZ-4 was to be a backup of CZ-3 due to the risk of LH/LO 3rd stage engine. I really don't see a technical reason today as CZ-8 has successfully flown and this one is still on paper. The rocket was the booster of 8th institute's 921 proposal, now they want to find a use of their work. It is like trying to make another 921 to take some market share. If it is a commercial company, there is no problem, but as SOE it is just wasting state budget.

It's a pieces of rock. If it were some earth shattering piece of news (cue speculations of preference), it would have been spotted long ago. Earthlings have been observing the moon and every inch of it for some time. If it's a newly landed/ surfaced "alien" artifact, we'd see it land and fly off if we don't reach it first.

It won't take months to tell what it is because as soon as the rover gets close enough for cameras to shoot it properly, we'd have the answers. This would probably be weeks of lunar day/night cycling and rover moving towards it.

Not really, angular resolution of even Hubble cannot resolve small lunar features on the meter scale.

It could be an abandoned alien artifact.

If it is an abandoned alien artifact, it would have been there for some time, long enough to have been noticed by just one of the Chinese, American, Soviet, Russian, and Japanese (I think the only ones to have totally mapped the moon in its entirety with high resolution so orbiters for signals don't count) lunar mapping efforts. It is already said by the Chinese to most likely be a rock of some sort, perhaps a remnant of a collision with dispersed rock forming what is shown in the picture. It seems rectangular but the surface of the object might be the reason for that.

It could be an abandoned alien artifact but if alien, it's much more likely not an abandoned artifact. Well if it disappears then we'd know something's up.

Even though I am not a fun of this rocket, there is some progress of it.

This is the 1st stage oxygen tank (3.8m) made in November 2021. Apparently 8th academy's 921 proposal is not just on paper but development work of component, same as the chosen one's 5m. It still remain to be seen if CASC is willing to pay the money all the way to launch. There is parallel work on the super solid booster for a Ares like CZ-9, it may or may not see the launch ever.

Yep

But all the rocket startups in China are in the process of developing reusable liquid-fuelled engines now

There are 5 companies mentioned below, including Galactic Energy
