An, a young woman from the Muong ethnic minority, comes from a small town that spans nearly 10 kilometres alongside the Red River in Yen Bai province, northern Vietnam. The area is filled with fertile alluvium, making it ideal for growing crops such as good quality canna rhizomes. Vermicelli made from canna root is a very popular product in Vietnam, as it's not only healthy, but also fragrant, soft and chewy.
