What about those adopted children?

My aunt adopted a daughter and later gave birth to a daughter, but they are both very close. The biological parents of the first daughter are rich, but they want a son. Later, after giving birth to a son, they wanted to recognize my sister. My sister said no, and then when my sister was admitted to college, her biological mother died because she lost the blood of a liver patient because of massive bleeding during giving birth to her son. Now my sister is excellent and beautiful. What is important is that she has a particularly good personality and a particularly positive outlook on life. Haha, I'm so laughing! I was adopted, and I never wanted to find my so-called biological parents. My father had a tumor operation, and I waited in the hospital for a week, but my own brother never came back. Later, my parents bought me a house in a second-tier city and decorated it myself, and bought a set as big as my brother in a big city to help him decorate it. I think I earned it anyway. Anyway, I have to support my parents all my life. . . . Just judging people's problems. . If you are not filial, you will be more angry.
