The Cia-Cia tribe in Indonesia faces a challenge: their language, spoken for centuries, has no written form.
To prevent their language from disappearing, they've adopted Hangul, the Korean alphabet, as a way to write it down.
The children are learning Hangul in school, which allows them to preserve their heritage and ensure the language's survival.
This innovative approach highlights the importance of preserving indigenous languages and cultures around the world.
