Recently I encountered this concept from Chinese women, basically it urges women to be disciplined when it comes to who you marry and who you make a child with.

This concept urges women to not carry a child with men who : disrespect women, have unhealthy lifestyles, are violent, etc.

It is very powerful: women have wombs, wome need to be picky on who to carry the genes with.

Don't marry a random guy for the sake of being picked, be picky, be responsible for your womb and your children.
