Is the rural proverb "Sister sends her sister, and she will be poor all her life" true?

There are many folk customs in our country, especially in funeral and marriage, especially in rural areas. There is a saying in the countryside that "my sister will be poor all her life". What does this mean? In fact, this is a tradition in rural weddings, which means that when the bride gets married, if there are sisters at home, she is not allowed to send her sister to her in-laws' house, otherwise she will be poor for life. In rural areas, the bride will bring her family when she gets married, which is the traditional custom of "sending her to get married". Including bridesmaids and matchmakers, in some places, brothers or sisters can follow, but sisters can't. Because "sister" and "borrow" are homophonic and have a bad meaning. If you let your sister get married, it means that your sister will be very miserable after marriage, and there is nothing at home. Who do you need to borrow it from? And if you ask your brother to follow you to your husband's house, it means that if your sister is bullied at her husband's house in the future, your brother can support her, on the other hand, he also supports the bride. Of course, this is only the feudal thought of the rural elderly, and there is another reason that is actually more realistic. In most cases, the elder sister marries first and then marries. Strictly speaking, she is no longer a family member. The countryside is very particular about etiquette. Since you are born with a family to marry, your brother can go and your unmarried sister can go, but you can't marry your sister, because she is only half of the family. Although this statement is a bit strange, many married daughters in rural areas really have no right to speak in their parents' homes and cannot participate in many important moments.
