The misery of being born into a family that "prefers boys over girls"

My parents have 3 children, I am the eldest sister. My parents are from the countryside, so their thinking is somewhat conservative, very "male-dominated".

My father was the eldest son, so he placed great importance on having a son. When I was a year old, my mother immediately gave birth to twins, two boys. Even though we were only one year apart, I did all the housework, while my younger brothers just played around and watched TV.

Every Tet holiday, when the new school year starts, the children get to buy nice clothes first, then me. My parents always call me "wild duck", saying that when I get married, I will become someone else's child, only the son will be their child. Growing up in a family like that, I was deeply hurt.

I didn’t go to college, I only finished 12th grade, went to work, got married, and had a pretty good life. My parents saved money for my two younger brothers to study properly, and after they got married, their lives were better than mine. However, when my parents had the land that their grandparents left behind, and in their will, they divided it into two parts for my two younger brothers. They told me that I would get married and enjoy the blessings of my husband’s family, and not have anything to do with my mother’s family anymore.

Hearing that, I did not want to fight over the land, so I kept quiet and held back. However, I still felt very resentful inside. My husband and children all advised me to reclaim my rights once and for all, speak frankly to my parents, and treat my children equally. I really do not know whether I should listen to my husband and children or not. I hope everyone can give me some advice.
