As a sister-in-law, how to solve the phenomenon of her indifference to her parents?

Have a deep talk with your sister-in-law and tell her that he has parents himself. You want him to take care of your parents. You can ask him if your brother also takes care of your sister-in-law's parents. That's caring. Similarly, I hope your sister-in-law will have no problem taking care of your parents. Or, if your sister-in-law doesn't know how to communicate with your parents, then you can talk about your parents' living habits and so on. Or something that can make your parents happy, or if you buy something for your parents, you can give it to your sister-in-law, just say it's from your sister-in-law. This will not only ease everyone's atmosphere, but also make parents happy and make brothers and sisters look at you with new eyes.
