Does the eldest son have the obligation and responsibility to help parents take care of their younger brothers and sisters?

I think the eldest son in a family should help parents take care of their younger brothers and sisters regardless of their obligations and responsibilities. Brothers and sisters are all flesh and blood, and blood is thicker than water. There's nothing wrong with helping parents share. It is also a choice for the eldest son not to take care of his younger brothers and sisters and not to assume obligations and responsibilities.

I am the youngest in my family, so my sister tries her best to take care of me when she can feel cared for. Life at home was hard when I was a child. My parents get up early every day and work outside to earn money to maintain my daily life. I was taken care of by my sister when I was very young. She is the boss and can only listen to my parents. In daily life, my sister cooks for me, takes care of me and plays with me. Later, she needed to study far away and come back once every two weeks. She usually lives independently at home and brings me a lot of food every time she comes back from vacation. When I was in college, she went home on holiday and bought me a lot of things with her pocket money. Until she started working, she began to buy clothes and things for me with her salary, which saved her parents a lot of trouble. When I'm not in college, she always gives me some pocket money before I leave. When she had her own family and children, she also took care of me. She was worried about it all the way home during the holiday. No matter what I ask, my sister will try her best to help me. Since my sister took good care of me, it really saved my parents a lot of things.

This problem has been widely exposed in society. Many families are in poor condition. The eldest son and daughter are mature and responsible earlier. They take good care of their younger brothers and sisters, share the pressure at home and give them the best.

The eldest son's care for his younger brothers and sisters at home is more emotional and is not allowed to mention responsibilities and obligations.
