Remnants from the French colonial days and later from the French last stand. Hmong primary students on their way home with sweaters we distributed at their school, in old buildings on the grounds of a long abandoned church built over a century ago in the high hills of Lao Cai, and a farmer drives by long abandoned french weaponry, still in the fields at the Dien Bien Phu battlefield, just down this road from another school where Hmong children attend as boarders.
