The two sons of Maung Tint Dei and Shwe Nabay had grown up very strong and brave like father like sons, served in the court of (Pyi) Shri-Khit-Tra governor.
As usual the court sages, Ponnas slandered, making such a false statement about the two brothers that 2 strong men would seize hold of the court and power, the governor got frightened and felt unsafe, immediately adopting a sort of divide and rule policy, he tricked them into fighting each other bare hand without any weapon.
Thus eventually the younger brother fell down dead first, and the elder brother followed suit, thereby two brothers instantly becoming 2 Nats of Taung Ma Gyi Shin Nyo and Myauk Min Shin Phyu.
