How did you persuade your daughter-in-law when she was in conflict with local customs?

What else can I say? Of course it's straightforward. After all, she married me, and we are already a family, so there is definitely nothing to hide. Although she violated our custom, it cannot be changed. It is impossible to cancel this custom just because she is alone, so I can only make her accept it, but I will give her time to get used to it.
