The Hmong migrated to Vietnam from the southern China at the beginning of the 19th century. The Hmong minority group has been subdivided into branches classified by women’s costume, dialect and customs. For example, the Hmong of Sa Pa are called Black Hmong because of their predominantly black clothing. The most colourful sub-group are the Flower Hmong, found in large numbers around Bac Ha in Lao Cai province, who wear bright-coloured clothes with embroidery. Corn is the main staple of Hmong people, but rice is often grown on terraces watered with the aid of irrigation. Hemp is grown to be woven into textiles, and cotton is also cultivated in some villages.
