Does the younger brother have an obligation to provide education for his younger brother? My father asked me to do this.

According to China's General Principles of Civil Law, when a minor's parents are dead or incapacitated, grandparents or grandparents and brothers and sisters with guardianship are the guardians of the minor in turn.

It can be seen from the above provisions that brothers and sisters have the obligation to raise brothers and sisters, but they must meet several conditions: First, their parents are dead or unable to raise them; Second, their brothers and sisters must be minors; Third, their brothers and sisters must have the financial ability to support them.
