What is the relationship between the eldest niece?

Men call you big niece. This man must be your father's brother or younger brother. They love you. That's why I call you so affectionately.

Or a brother who gets along well with your father. In order to close the brotherly relationship with your father. Give you a lovely name.

Someone begged your father. I'll call you that kind and honest old man. No culture. You helped them. To thank you. Like the younger generation and children. Call you your niece.
