Ms. Zhang's father was deeply infuriated by Ms. Zhang's firm attitude.
He kept cursing, "Evil daughter, evil daughter!"
But it was impossible for him to sever ties with Ms. Zhang, because after the Zhang Family had cut off relations with the other branches, their family had become much smaller. Although they were not so downtrodden that others could bully them, they found themselves without support when problems arose.
Moreover, those other branches would occasionally come to harass them, which made Ms. Zhang's father feel even worse.
