Hi, that's not at all epresentative of chinese healthcare.
They have nationalized health care and most conditions, from sprained ankles through childbirth up to cancer, are covered at extremely low costs to Chinese citizens, so this might be an outlier where she has something extremely severe or so rare that the treatment is unavailable within China.
A likely scenario is that they are choosing a treatment that national healthcare doesn't offer but is available for purchase outside of the health care system.
