How to better handle the relationship between brothers?

In dealing with the relationship between brothers and sisters, the main principles are to care for each other, help each other and think more about each other. The society also says that getting rich first will help you get rich later. Therefore, people who live well should take the initiative to help those who live poorly, and don't have the idea of being afraid of losing money. I am not the boss of my family, but among my brothers and sisters, I have been more capable since I was a child, and my economic conditions are better than others as an adult. So the responsibility of taking care of parents is mainly borne by me, other brothers and sisters, nephews, nieces and so on. I also give help according to everyone's different situation. The other is to ignore what brothers and sisters did wrong. Because my parents praised me and valued me more since I was a child, it also caused jealousy among my brothers and sisters. Sometimes I don't appreciate my help and even sow discord behind my back. If you want to see my jokes when I am in trouble, I hope I am unlucky. But I never care, I should help, I should do what I should do, and I don't want to return.
