As much as I think the aunt deserve to be treated that way and worse, I still think that JiuQing is being overly reckless in how she is acting about it.
Half of the time she makes reasonable objections, but the rest of it can easily be mistaken as pettiness so I find it hard to believe that it isn't backfiring and just making the stupid father mad.
Making the aunt stay in the worse courtyard is reasonable, but forcing her to kneel at night like that is just asking for trouble.
