Incense smoke, coiling lazily upward, can evoke memories, induce a feeling of relaxation and even take our minds to places we've never been to. The burning stick is reminiscent of another time, another place－as the song goes, "the images unwind... in the windmills of our mind". Incense maker Lu Wen believes history is not just words on paper, but that it can come alive in the imagination triggered by smell.
