I'm looking for a couple of things about this song.

1. I've seen a video setting footage of the Tiananmen incident to this song. The singer sounds like Wang Hong in this, but IIRC she sings throughout the song. I'd like to track down the video, on youtube or elsewhere, as well as the ID of the singer.
2. I'd like to know the story behind the song. I've found a Chinese wiki entry for the song, from which I gather that the song was written to remember the 1979 Sino-Vietnam war. When was the song first performed, and who were the performers? There's a link from the wiki to a 1987 performance, which is a duet between a soldier and a wheelchair and a woman, presumably Wang Hong.
