@lethal09 xianxia is like wuxia yes,but it does not necessarily focuses on a female protagonist
see wuxia mainly focus on martial arts(wu) (and ofcourse cultivation)
but xianxia on otherhand focus only on cultivation on immortal(xian)
simply put..
wuxia covers most of mangas that are not only chinese for example in korean(mangadex.org/title/59692/i-m-a-martial-art-villainess-but-i-m-the-strongest) or in japanese(mangadex.org/title/3132/dragon-ball)
but xianxia is exclusive to chinese immortal cutivation
so it is more effort than worth to add a tag that does virtually nothing
