Bo Min Maung had a younger brother, Bo Min Yaung, who had a great impact on Aung San's patriotic outlook. The younger brother was remembered by Daw Thu Sa as being popular in his hometown for his handsomeness, strength, writing ability, and swordsmanship, which he practiced every day. King Mindon employed him in diplomatic service, and by the reign of Burma's last king, Thibaw, he had been appointed to administer the region of Myo Lu Lin, close to the northern side of the Pegu Mountain Range in Upper Burma. After learning of King Thibaw's abdication and subsequent exile to western India following the brief Third Anglo-Burmese War in 1885, Bo Min Yaung became angry, and made up his mind to resist the British.
