Big Sister Mo Yaner, in Xuexue's past life memories, was someone with a straightforward nature. After getting married and because her husband's family was poor, the Mo family members didn't like her coming back. Every time she came back, Old Lady Mo would express her discontent not so subtly—nose not a nose, eyes not eyes—and during meals, she would slam the bowls down so hard they would clank resoundingly, saying things like "The money-losing daughter who's been married off has such thick skin, and still shamelessly comes back to her maiden home to freeload."
Madam Xie had always been fearful of Old Lady Mo. Although her heart ached for her eldest daughter, she dared not speak out, knowing that if she made even the slightest noise, she would surely attract a brutal beating from Old Lady Mo.
Over time, Mo Yaner became reluctant to come back as well, only returning for Madam Xie's funeral after she was killed by Auntie Sun.
