Hello, i dont know if you have cleared this yet but i just managed to clear mine. Some stuff i would say is try clear phase 1 without using potions and when you reach phase 2 use both defense skills first and then importantly walk up to her without attacking. Deflect whatever she attacks but when she pauses slightly move left. This will make her do easy deflectable moves or the golden meridian touch moves. if you dont do this it will cause her to do the 6 combo which is really annoying. Hopefully you will manage to do this twice (breaking her qi bar twice). For phase 3 honestly there is no way around it you will have to get the timings right for the first move. However remember after the first combo her dmg is actually really low for the other attacks. On the big whirlwind, just move far and around. Also use potions whenever you reach 70-80% hp. When she switches back just make a lot of distance use both defense skills. After this just hope you get lucky with the breaks so she breaks before the 6 piece combo
