Does the elder sister have the obligation to provide for the younger sister to go to school?

Legal analysis: It depends. If the parents are alive, the elder sister has no ability and obligation, and the mutual help between brothers and sisters belongs to the scope of moral adjustment.

Legal basis: Article 1075 of the Civil Code of People's Republic of China (PRC) states that brothers and sisters who have financial means have the obligation to support minor brothers and sisters whose parents are dead or whose parents are unable to support them. Brothers and sisters who have the ability to be raised by brothers and sisters have the obligation to raise brothers and sisters who lack the ability to work and the source of life.
