People who are not family don't enter the same house.
The grand words of Song Lingsu and his brothers to Qi Zhen (a veiled threat) reached the ears of Song Ci and the others, bringing Song Ci great joy, and she couldn't help but exclaim how much it was like their ancestors.
Oh, the ancestor here is naturally her, one of Song Ci's classic lines, don't let vanity distract you!
Brothers should be like this; the Song Family has few sisters, so they treat their cousins as sisters too, which is great. This also gives the married aunts a lot of confidence.
After all, at home, you rely on your parents, and when you're married, you rely on your family and brothers!
And being from the same family and ancestry lets you support each other. Why worry about the family not prospering or the clan not enduring long?
