In the middle of reading it now. Its a dual effect. One is that its natively written in chinese so a lot of its cultural stuff like the beginning will go over english readers heads not knowing that the chinese people literally had an violent orwellian book burning period of their history against academia. I imagine it was an attempt to pull readers in emotionally but Its hard to be emotionally invested in a cultural history you have no knowledge of and its paced badly.
The second is that the sci-fi genre is unfortunately nearly universally populated by nerds with good ideas pretending to be writers. This results in very interesting ideas and thought provoking settings being brought low by eye wateringly boring characters, piss poor narrative through lines, souless or confusing writing style, ect. Go ahead and try to read an Asimov book or Dune and you'll realize This was always the case for decades at least.
In fairness to the authors its hard to tell a civilization spanning futuristic world ending drama while also keeping it grounded.
As an enjoyer of sci-fi you kind of just have to power through the slog of some dead writing to get to the interesting concepts. I've never had the pleasure of reading a harcore sci-fi novel that was also an excellently written character drama. The only soft sci-fi book that pulled off the balance and stuck the landing was The Martian.
