"I love her although she does not love me."
Translation:Tôi yêu cô ấy mặc dù cô ấy không yêu tôi.
Hi DUO, you said at the beginning of this lesson that mac du and tuy nhien are completely interchangeable, and to let you know if one is not accepted in place of the other. I am letting you know! I had this sentence exactly as above except I used tuy nhien, and it did not accept it.
