Insightful read into the cultural context of the Chinese language! Thanks for writing this.
Many modern English writers commit the sin of writing of heroic deeds in distant times with modern language.
I'm sure a lot of English writers struggle with this writing for different times. There are trade-offs either way. I think the best way is to get creative. I was impressed with the way the sci-fi show Firefly addressed it. They spoke mostly vernacular English but swear words were morphed versions of current ones (goddamn -> gorram) or Chinese language insults. It tied well with the general anachronism of the show, it being a cowboy western set in the far future, far from Earth.
