We are in the Quan Hoa mountains in the Northwest of Vietnam. It is one of the poorest and most isolated regions in the country. Here, most of the inhabitants live on less than a dollar a day.

Some of this bamboo is transported on rafts… Makeshift crafts, assembled in just a few hours, are sent down the twists and turns of the tumultuous river Luong.
