How to distinguish adoptive parents from biological parents?

My parents who gave birth to me and raised me gave their lives for each other; Give birth to me and don't raise me, ten fingers can be reported; If you didn't give birth to me, how can you repay me for raising me? But it depends. If your biological parents really can't support you because of the economy or their own ability, I feel excusable, because after all, they gave you life and gave you away only for a better quality of life. But since it's best to leave you alone, it's an undeniable fact that your parents gave birth to you, but it's even harder for adoptive parents to raise you. As a mother, it really takes a lot of time, money and energy to raise a child. There is also a family that values boys over girls. Such parents had better not provoke them. They ask their daughters to send them out not because they miss their children, but because their daughters can "exchange bride price" when they are older. This kind of parents is what I spit on most. In this world, loyalty and righteousness are inherently difficult to be satisfactory. Listen to your heart.
