He delves into the everyday lives, customs, and beliefs of the Lolo, providing a rich, firsthand account of a culture that existed before significant societal shifts in the region. Through Goullart's observations, the reader gains insight into the complexity of life in these remote areas and the resilience of the Lolo people in navigating a changing world.
