To address this, Yangan Mro, a trailblazer in preserving Mro culture and language, wrote the book Nammo Tsen Kiyak Mi in the Mro language, detailing the biographies of the seven Bir Sreshthos. Renowned for creating the first Mro dictionary and grammar book, Yangan began this mission in 2017 after a student expressed a wish to read about these heroes in their native language. After eight years of dedication, the book has brought joy to the Mro community, enabling them to explore their nation’s history in their own tongue.
