The consequences of the eldest sister-in-law living in her parents’ home
Feng Shui believes that if a woman returns to her parents’ home after a divorce, it will damage the fortunes of her brothers and sister-in-law, especially their emotional problems. It is easy for them to quarrel all the time and their relationship is not harmonious, which in turn affects the relationship between mother-in-law and daughter-in-law.
Don’t worry about your natal family’s affairs because you are already married. Logically speaking, you cannot live in your natal family’s family for a long time. If you live in your natal family for a long time, be sure not to meddle in your natal family's affairs, especially those of your younger brother or elder brother's family.
Later, I heard from an old woman that her sister-in-law’s permanent residence in her natal family would lead to infertility among her younger siblings. Although it is a bit superstitious, I also think it makes sense. She is here, and I feel upset just looking at her. Solemn statement: The answer content is for reference only, please do not be blind and superstitious.
