编辑同志: 我是江苏人,兄弟两个。我24岁,哥哥27岁,在我们十几岁的时候,父亲就去世了。又过了两年,母亲改嫁,把我们也带到了新家。可不到一年时间,我生父那边的一家人就到我们家里来,说要我们兄弟两人出钱来养爷爷的老。而爷爷有两个儿子,四个女儿,都可以养他。这七八年来,我们兄弟两个都不在家的时候,他们经常十几个人到我家里来打我妈和我后爸。我想问,我们是不是有义务去养爷爷的老?我们怎样做才能不让他们再打我妈和后爸? Edit comrades: I am Jiangsu, two brothers. I am 24 years old, my brother is 27 years old and my father died when we were teens. Two years later, my mother remarried and took us to her new home. Less than a year, my father's family over there came to our house and said that we two brothers and brothers must pay to support grandfather's old. The grandfather has two sons, four daughters, can raise him. In the past seven or eight years, when neither of our brothers was at home, they often came to my house to beat my mom and my daddy. I would like to ask, we are not obliged to raise the grandfather's old? How can we not let them beat my mom and dad?
