I realize it doesn't have English subtitles, so I'll summarize some highlights of what's in there:
* interviews with scientists and engineers working on the project
* trajectory of the spacecraft and lots of talk about the challenges of reducing velocity for landing
* historical overview and context for why Mars exploration is important for science
* what to expect in the future landing and when it'll happen
It's pretty similar to video programs that NASA produces. Not sure what information you're expecting that isn't out there, but I think you're attributing to secrecy what is more easily attributable to people not translating open public reports into English.

Here's the process for how the landing site was selected:

I think this is more open than the Zhurong information has been, but I'd be happy to learn more.
Not only space. This is the reason it always feels like the west is collapsing while Chinese hegemony is inevitable. Western news outlets publish hyper-critical editorials about western governments that wouldn't be allowed on state run media in the east.
Obviously, in China, they are allowed to criticize even less, but westerners do not read chinese news.
What's more, nor does anybody else.
So the image of China doing very well is not for a lack of bad press. If you read publications about China over the last decade or so, it's a constant slew of doomsaying, and negativity, mostly about problems that turned out to be very surmountable or insubstantial.
The image of China becoming more and more hegemonic is simple: look at their economic growth. Look at the size of the nation. Look at their intellectual culture. China being a very powerful country is a return to a historical norm, and is a totally reasonable development given how big their population is, how skilled it is, and its values.
Meanwhile, the west is seen as falling apart because it is having a massive identity crisis which involved things like the leader of the free world bragging about how big his nukes were on Twitter.
I'm not frankly particularly enthusiastic about China as a world power - I'm not a fan of confucianism, for example, and CCP spokespeople talk like politicians from dystopian sci-fi, but I think it's profoundly wrong to think China is deceiving the world with its masterful press controls. Far from it - the direct censorship and press controls are very blunt mechanisms most states have given up on because they don't work and if you're good at media, you don't need them anyway.
I guess what I'm saying is, if China becomes a hegemonic power, it won't be militarily, it'll be economically, sort of like monopolies/oligopolies today, and those kinds of powers can be resisted much more easily by soft power methods.
The economic growth argument fails to impress it. Every nation that goes through an agrarian->industrial conversion experiences huge economic growth until they transition to a developed service sector economy.
Much is made about Chinese infrastructure building, but did you ever look at what was done by FDR under the New Deal? 1 million kilometers of roads built. 10,000 bridges. 40,000 schools. etc. The Tennessee Valley Authority built tens of thousands of miles of electric grid. Or take progress in the Space Program of China. It looks impressive, but Von Braun founded the US rocket program in 1945, and NASA was founded in 1958. 11 years later, there were men standing on the moon.
Things only look fast now, because developed Western economies have settled into long term 2-3% service oriented economy growth. With China's declining birth rate, rising cost of living and wages, it too will experience a slowdown.
So, go read the book.
Look at Wikipedia: CNSA is under the jurisdiction Ministry of Industry and Information Technology (工信部）, which itself is a civilian department, at least not less so than US department of energy.
What's the proof for your claim that CNSA is not a civilian agency?
"State Administration for Science, Technology and Industry for National Defense" is a civilian ministry within the State Council of the People's Republic of China and is a subordinate agency of the Chinese Ministry of Industry and Information Technology and the superseding agency of the Commission for Science, Technology and Industry for National Defense (COSTIND).
You might as well think Ministry of Industry and Information Technology is in charge of civilian and military application of relevant tech in manufacturing and information tech. Just like DoE also manages nuclear weapons.
The DOE/NNSA has federal responsibility for the design, testing and production of all nuclear weapons. According to https://en.wikipedia.org/wiki/United_States_Department_of_En...
I am unhappy about the parent, is that people are commenting things without sensible realization of their own limitations. I frequent here, is because of people are far more sensible about their limitations on almost all topics.
But that sensibility is non-surprisingly low in China-related topics.
Given how many classified Shuttle missions[1] took place over the decades it was in service, and how the Hubble Space Telescope was likely a clone of a spy satellite, I don't think it's fair to say that NASA is entirely a civilian agency.
