The best version I heard was the one played by a blind old man sitting in front of a book store at Xin Jie Kou, Beijing. His Erhu was very poor. It was just two piece of plain wood, without any painting on the surface. He played so sentimental that almost every one passing-by slowed his steps.
I tried to play it with violin, but I do not think it is good at expressing such Chinese-special music.
