Where does this sentence come from?

An old adage, without a source, is similar to a proverb. "Poor men and rich women" was regarded as the "golden rule" in ancient times. In fact, "poor" and "rich" here are not only material meanings, but also reflect the different expectations of China parents for their children. The main meaning of a rich girl is to cultivate her into a "good family" The poor support of boys is a kind of frustration education, in order to make children become "courageous people." To some extent, this educational concept has some truth. Men should be self-reliant, have suffered from childhood, and those who have tempered their will can do more things. And the girl raised by "rich people", the superior life is like a powerful immune needle, so that she can stick to good moral concepts to resist the temptation in the future and become a well-informed, elegant and beautiful woman. In addition, in terms of gender differences, boys are naturally aggressive, adventurous and controlling, while girls are more predictable and stable, and like to communicate harmoniously. Therefore, it is in line with children's natural gender differences to give more love and attention to girls and more challenging situations for boys to conquer. However, this statement also has some drawbacks: girls raised by "rich people" may be spoiled, unable to be immune to temptation, and may even form the values of "too poor to love rich people"; Boys who grow up in "poverty" may lack care when they grow up. On the one hand, they are insecure, autistic and inferior, on the other hand, they are too self-protective, aggressive and even hate family and society. In fact, in addition to the material foundation, the core of "poverty" and "wealth" should be the family's educational methods and concepts. In fact, it is necessary to educate both the "poor" and the "rich" children. "Wealth" refers to sufficient investment in education, caring for children, broadening children's horizons and knowledge, and allowing children to grow up in a good environment. This is the "wealth" and "pet" that all children should have. In addition, "poor support" means that no matter whether the family is rich or not, children should be properly tempered to consciously cultivate their independent, brave and self-reliant personality, so that they can understand the hardships of life, know how to choose, know how to be grateful and know how to be satisfied, so that children can better create a happy life.
