There are three women in the family, the older one is disabled, the second one is a door-to-door son-in-law, and the third one is married far away. Who should parents support?

Every child has the obligation to support his parents, but it is not necessary to be so clear about supporting his parents, if the sister relationship is good. The eldest daughter is disabled and is in a weak position in economy and action. The second daughter can take care of her parents by recruiting a son-in-law. Three girls are married far away, so it is inconvenient to take care of their parents, so they can support them more financially.
