What about the military setup? Are they doing 府兵制 or 募兵制? Common soldiers are drawn from which social rank? How does the leadership work? Is it more like Tang where the generals / local commanders have a lot of power & autonomy, or more like Song where the central government put up with oodles of red tape to prevent generals from having real power?

BTW, how do you find fics in general? Are you getting recs from somewhere? Or are you using some kind of search service/app?
