:D it means you are very good-looking. you can say "xie xie" for reply. good luck:D

i think you want to say ni hen piao liang. in china the meaning is you are very beautiful !we always replay "really ! thanks ! " = "zhen de ! xie xie !"or "you are good !"="ni ye hen bu cuo !" or "so lovely words"="ni zhen hui shuo hua !"

有点看不懂了，呵呵。不过应该是说你很漂亮的。 我想他本来想这样说的： 你 很 漂 亮 嘛！ ni hen piao liang ma !
