In the mountainous province of Lao Cai, the H’mong people continue to preserve many unique aspects of their cultural heritage. Among them, the khen—a traditional bamboo wind instrument—is more than just a musical tool. It is the voice of the mountains, the soul of the Hmong people, and a link between past, present, and future. To keep the khen alive, generations of Hmong have carefully protected and passed down this tradition.
