Yes. Because their parents are busy, the elder sister and younger brother keep each other company and depend on each other for life. Play games together. Do homework together. Going to and from school together, etc. Until her sister got married and started a family, she also cared about her younger brother who grew up with her. Just like Song Yunping in the big rivers. She and her younger brother Song Yunhui were admitted to college at the same time. Because of my family background, I can only choose to give up on my own. With tears in my eyes, I wrote down my application to go to college. I wholeheartedly hope that my younger brother will succeed after going to college. So the sister's love for her brother is selfless. When you have a good sister. It should be happy and joyful! Personal opinion, for reference only.
