What does it mean to have a poor son and a rich daughter?

"Poor boys and rich girls" is a "parenting method" for China people to educate their children. To support a poor boy is to work hard on his mind and bones and let a boy take on a big responsibility. Enriching girls means broadening their horizons materially and enriching their thoughts spiritually, so that girls can be independent, well-informed and happy all their lives.

There is also a saying to express children's education: "There are many rich ladies, but there are few handsome men since ancient times." This sentence means that from ancient times to the present, most wealthy families can cultivate intelligent and virtuous women, but boys from wealthy families rarely get ahead.
