In fact, the story of the female Voldemort is also easy to understand, that is, "the devil who supports his younger brother." It is the homonym given by netizens to Fu Di Mo.

That is to say, it is okay for a woman to help her younger brother. After all, family ties dictate it. But women like the "Brother-supporting Devil" have helped their younger brothers to the point of going crazy. They are willing to hollow out their own families, even at the expense of any interests and rights of themselves and their spouses. She also wants to subsidize her natal brother, take care of her natal brother's life, marry her, have children, and even take care of her natal brother's children's education, marriage, and children.

As of now, "the devil who supports younger brothers" no longer refers specifically to older sisters, but also includes younger sisters who dedicate everything to their elder brothers.

"Fu Di Mo" means that this woman's life is ruined. Fu Di Mo turned over all her salary before getting married, and then came to harm her husband after marriage, asking her husband's family to pay for her brother. If you work, your younger brother will take care of everything from wedding gifts, buying a house, and raising children; if your younger brother is poor, he must get rid of poverty, and if he gets rid of poverty, he must become rich; you have no share in the interests of the family, but you are responsible for providing for him in old age, and you are willing to do so.
