That would need reusability to avoid bankrupting the country.
I assume that by 2035, China would definetely have its own reusable rockets

I assume that by 2035, China would definetely have its own reusable rockets
Nowadays aerospace activities are expensive for all countries. Even if China makes out her own reusable rocket launching system like US did, lowering launching cost by one digit or even more, it's still a business without enough market demand and profit.
So in the future, with more national fund CNSA may pratice much more aerospace exploration projects than they do now. But more than one thousand launches every year by 2045 is totally out of my imagination.
It maybe 1000 separate objects lunched into space per year rather 1000 separate boosters launching. 1000 separate objects is not only feasible, but one could easily see how it could be used and needed. Micro-satellite constellation, for example.
10k tons is more difficult to envision. I don’t think bulk space mining for use on some body other than where it is mined twill be practical for the foreseeable future. Only mining of extremely valuable minerals in small quantities can be economically feasibly for that.

since there is no up, down or sideways on space, how is a bunk different from a coffin?
I mean... how do they look to you (or anybody) at a glance? The Tianhe ones look like bunks you'd find on ships or trains, whereas the ISS ones look... exactly what they would look like.
An astronaut doing an ISS tour did state the pods were indeed located and formed part of the "floor" of that module, so there's that.

It will be something psychological the astronauts will have to deal with. The brain will see the computer/equipment cabinets as standing vertically on the "floor" of the space station. The astronauts will see the bunk beds as lying on the "floor" and therefore will see themselves sleeping "horizontally" in the usual way.
Of course, these things can be psychologically reconditioned but why not give the astronauts the luxury of not having to do so every time he "lies down" to rest or sleep?
As @Quickie said, there is up and down in the head of the astronaut, you can clearly see that from the video footage that the first astronaut is sitting on the floor when working. The next one immediately turned himself up straight after entering the cabin.
There is no gravity for sure, but definition of orientation (up and down, left and right) is still necessary and beneficial for practical purpose besides its psychological purpose.
And last I don't think even on earth that "up and down" have strict definition or even necessarily related to gravity. For example in the north hemisphere people often say north is up, what happens to the people in the southern hemisphere? The terms are just for orientation.

Zhang Zhi is the chief designer of the new manned launcher (AKA 921) and former chief designer of CZ-2F.
The (new) near earth orbit manned rocket is derived from the moon rocket. Near earth payload capacity close to 20t.
This seems to indicate that CZ-7 will not be developed to be manned rocket for the new spacecraft as planned before. This is natural because CZ-7's manned mission was planned before the decision of 921. Having the same line of rocket and spacecraft for both near earth and deep space mission is a better choice.
The near earth 921 would be the single stick version with a reduced 2nd stage (one YF-100M instead of two) and no 3rd stage.
