On the topic of whether the elder sister should raise the younger brother, I think it is necessary to analyze the specific conditions.If my parents were not patriarchal, they would be as good to me as my brother. If I didn't suffer great harm in family of origin, I would help raise my younger brother and try my best to tolerate his little temper and childishness. Because, after all, we are related by blood, he is my only immediate family in the world, and human beings are emotional animals.But if it's like this in the movie, my parents only love my younger brother, are ruthless to me, don't give me any care, and even sacrifice everything I have to make my younger brother. And my brother is so capricious. Then I can't break my wings to raise him. Because, after all, I am a child and need to be cared for. I need to bear so much pressure at a young age and suffer so many unfair treatments, which is a great harm to myself. I have never been warm in this family, how can I warm others?The cultivation of people's character has a great relationship with the influence of family of origin. How to choose, in fact, should depend on the practice of family of origin.
