You need at least a certain amount of astronauts to make a viable base.
Otherwise all you will get is a flag and footprints mission like Apollo.
Agreed, It should be a long term mission otherwise Chinese missions as impressive as it is won't be able to outshine Apollo ones but still machines does the job better sending a rover equipped with 3d printer makes more sense than sending half a dozen astronauts

Screen captures from a Chinese TV report on the ongoing development of the Long March 9 superheavy carrier rocket for Mars and deep space exploration. LM-9 has a diameter of 9 meters and first flight is scheduled for 2030.

Does anyone have a link to the video, preferably on Youtube?

This first image shows part of an engine:





A size comparison of various LM family members. LM-9 dwarfs LM-5.

What a waste of money. Anything larger than LM-5 is a waste.
China should instead focus on cost reductions and rocket reuse.
You can do on-orbit assembly of whatever you need to make a Moon or Mars mission.
Those ultra-expensive Saturn V like launchers are pointless.
The Soviets made Energia and it was relegated to the trash heap of history.
At best they continued the RD-171 rocket engine design. The rest was pure waste.
Of the Saturn V rocket only the RL-10 engine was retained into use.

Elon Musk and Jeff Bezos' massive rockets (TSTO Starship, New Armstrong) are pointless also.
Even if they are reusable no one needs that kind of payload capability. Or will for the next decades.

Just look at Korolev and Chelomei's late designs for a manned Mars mission.
They didn't use chemical propulsion for manned Mars missions. They used nuclear or solar-electric propulsion.
This means the required payload mass is way lower than with chemical rockets.

Huh, so "complete demonstration and verification" of the Tengyun two stage space plane by 2025, are they going to start flying the Tengyun (or at least a scaled down demonstrator still capable of orbital insertion) by 2025?
