Among the Palaung
The Palaung are another tribal group living in the Golden Triangle area, primarily in Myanmar. Traditionally the women were easy to recognize from their large silver or gold metal belts (in the village I visited, the belts were silver, so this tribe is known as Silver Palaung), and the men from their expansive chest and leg tattoos.
Both practices have mostly died out. I did have tea with one 96-year old man covered in tattoos and his youngest daughter (whom he had at the tender age of 76), but the practice was frowned on by the British and is now almost nonexistent.
