编辑同志:我父亲早年去世,母亲含辛茹苦把我们兄妹三人抚养长大,现在都已经参加了工作。这几年,母亲的生活费用全部都由我们兄弟二人承担,由于收入低,存在一定困难。我们提出要妹妹也负担一些赡养费,她却说:『我已经是出嫁的女儿,没有赡养老人的义务。』请问,她的说法对吗? Editor's Comrade: My father died early in his life. His mother worked hard to raise and raise three of our brothers and sisters, and I have now joined the work. In recent years, the cost of living for my mother is entirely borne by both of my brothers. Due to the low income, there are some difficulties. We proposed that my sister should also pay for alimony. However, she said: "I am already a married daughter and have no obligation to provide for the elderly. Excuse me, is she correct?
