She's doing a lot of yolo shit that you just can't afford against a character that does triple your damage off of a single touch. Against Liu you literally just challenge his space after a successful d1,b3xx and keep walking backwards until you're in the last quarter before the corner, then you try to keep him out some more but he'll get in, which is when you yet again either attempt to switch sides or challenge his space again. It's not a horrible matchup for Jade but she's not winning it.
