Actually I'm thirsty for a lesbian wuxia flick, but after a long time searching, I belive there's no such thing (outrageous)
One day hopefully. Have you seen the famous historical lipstick add? https://twitter.com/congeebrain/status/1356324710292733952?s=20
The closest I can think of is maybe Princess Agents? The FL never says she loved the SML (no matter how much he pressures her to) and insists that she doesn't love the ML (and just doesn't like that the SML used the ML's affection for her to lure him into a trap) until pretty much the end (although her actions in the end suggest that she might've fallen for the ML by then, he's half dead at that point....). She kisses the ML on the forehead when he's dying, but as far as I can recall (admittedly, it's been a while) there are no other kisses.
TL;DR It's a wuxia drama that is focused on a powerful FL and although there's a love triangle, if you squint you can probably get through it and tell yourself that the FL never had full on romantic / fell-in-love feelings for any of the guys chasing her.
Fair warning, the special effects / cinematography are pretty awful at certain points and it has a cliff hanger ending.
And maybe also try Mr. Sunshine? It's a historical drama (set in Japanese-occupied Korea, not ancient China) centred on a FL (the same actress who plays the handmaiden in The Handmaiden) who is a "sheltered" and "delicate" noblewoman by day, and a trained sniper / rebel by night. There is a romantic storyline but the FL never really gets with the ML (except for a marriage of convenience), there are no kisses and virtually no skinship, and the FL always chooses to keep fighting for her cause over pursuing romance - even in the very end. And there's a nice close-quarters fight between the FL and SFL [x], [x], [x].
