I have been reading the English translations and the characters and especially their dialogues feel very fake. I do appreciate the hard science aspect of the books but the long monologues, kids speaking like middle-aged philosophers, and army personnel being one-dimensional macho men breaks the immersion for me. It has the depth of a 1980s low-budget thriller.
I don’t read a lot of hard science fiction or translations of Chinese books. I don’t know if this is genre-related.
The translator is a novelist in his own right, and his Dandelion Dynasty series is quite good. It’s not the translation. I suspect it’s a combination of it being a hard-sf “ideas” book, and different national styles in novel writing.
