The documentary films not only let us travel through time but also present Kavalan and Ketagalan culturals, recording phonograph records and 16 centimeters movies which were scattered to different collection organizations in different countries and collected by the westerners and Japanese hundred years ago. The films have both recorded the images of people and tribes in detail and retraced the historical memories since1990. They also present the continuous tribe vitality of the day and connect the dispersed national destiny to the way of rebirth and recurrence.
In Aug. 1993, I found that I was the descendant of Kavalan unexpectedly and then I seeked positively the historical and political reasons why Kavalan lost Yilan Plain and why they were compelled to move. I started to record not only the sacrificial offering culture and life appearance of Kavalan but also the way how they demanded to restore the name of the tribe.
