"""According to memories of some people, a Lao clan migrated from Laos into Vietnam, passing Thanh Hoa and Son La on the way to find new settlements about 300 years ago. In the Northwest, apart from the Thai, the Lao are growers of long-standing wet-rice cultivation. The Lao are also called Thay, Thay Duon, Thay Nguon; their other names are Phu Thay, Phu Lao. Being agricultural dwellers who are familiar with wet rice cultivation and fishery, the Lao concentrated by rivers and springs. They build houses leaning against montain slopes and facing valleys and rice-field"". (From the Publishing House).
