《被遗忘的声音》是一部关于川江号子及其传承人曹光裕先生的纪录片。川江号子作为一种民间歌唱艺术，在受流行音乐潮流影响的中国年轻一代中，其魅力已经逐渐减弱了。然而，民间艺术就像是年轻一代和老一代之间的桥梁，它不仅会让我们重温过去，了解我们祖辈的生活方式，也传递着精彩和独特的民族传统。那么，这样的民间艺术该如何流传下去并发扬光大呢？

Our film, An Unforgotten Song, should become a thought provoker to all those who forgot their roots. I wish the Chuanjiang Haozi finds its rightful place again, in the hearts of the Chinese people and reverberates again in the gorges of the Young China. This film is a salute to all those artists like Mr. Cao, who are still fighting the odds and nurturing the traditional and cultural arts of China and trying to keep them alive. I believe, if my film could motivate at least one young fellow to learn Haozi, it’s worth all the awards in the world.
