Amongst the works emerging from this nascent period of Vietnamese anthropology, Henri Oger's Technique du peuple Annamite, or Mechanics and Crafts of the People of Annam, stands out for its unique insights into the lives of residents in northern Vietnam in the early 20th century. Unlike many of his contemporaries who focused solely on high-culture elements such as art and architecture, Oger ventured into civil engineering practices and traditional customs. His study covered a wide range of topics, including handicraft professions, daily routines, and commonplace objects, demonstrating a comprehensive exploration that extended beyond the realms of the elites.
