Also, was your introduction to wandering earth the movie? If so I suggest reading the trilogy.
Indeed nature of the story is to focus on individuals. Still for example interstellar, you fully follow the dad/daughter and all that tubular space station building just happens completely off screen. And its assigned to the brilliance of the daughter instead of the coming together of people (how i interpret it!) curious how you view that for example :)
I think the 3body problem has a similar theme, the protagonist is central to the story, without him stuff does/doesnt happen, but the infrastructure (which in the main happens off camera) is built and deployed by the many not an individual, of course some solutions (trying not to spolier anything) are dependant on one individual.
I guess my point is that there isnt much difference between western and chinese sci-fi but chinese sci-fi also has to please the chinese government to be allowed to be published, so that also needs to be considered.
