Danyo has a lot of words about this matter. I'll add an only word based on our culture ;pious .It means filial piety.We are influenced from Chinese, from Confucius: The only one child is the boy, the eldest; Ten girls are nothing. There are some families with many generations. The mother is an angel. She takes care the first and the second generation..... If she can. She used to be in diet so she didn'nt have any diseases. The boy in oriental culture is never parasite so he can't economically stand on his own. He always has a right , may be so called authority. In reality, boys are always so smarter to make thei r families to live better.Rich or poor depends on his talent.In modern famlies, girls are equal to boys If children cannot economically stand on their own , parents will support them. It's normal. it's responsibility.
