月梦（Moon Stream）

The song expresses the blue feeling of missing a friend. Just one year after the song was released, the author of the song, 張炬, was tragically killed in a car accident at the age of 25, and then the song naturally became a song for friends to remember 張炬, which is really the strange fate of this song. The harmony part at 3:36 of this video is sung by the author.
