Hello! I'm looking for help with a phrase I want to put in an assignment I'm writing to perform in a speaking exam. In this part, I'm speaking about my fictional grandma. So far I have written “ 我今天跟我姐姐去看望我们奶奶。她住在桂林郊区。” However we have to get a 是。。。的 sentence in and I'm struggling. I'd like to say “ 她是 live alone 的 ” 可是我不知道怎么说！ Can anyone help me please? The phrase needs to say that she lives alone/on her own.
