From time immemorial we call ourselves Zo (Jo, Yaw). This fact had been admirably recorded by Father V. Sangermano since the year 1783 when he made his headquarters at AVa then considered by the Burmese as the centre of the universe. A few early writers also recorded the fact that we are Zo (Jo, Yaw) people inhabiting areas between Assam and the Irrawadi river e.g. Dr. Forchhammer, and also in Maung Tet Pyo’s book “Customary Law of the Chin Tribe” and by Sir Arthu Phayre, etc.
