Aung San's parents were U Phar and Daw Su. U Phar, his father, was very introverted and reserved. According to Aung San, U Phar studied law and passed his bar exam third in his class of 174, but was not a successful lawyer, and his mother took much of the responsibility for raising the family by doing business. U Phar died at the age of 51 in May 1931 after a two-month illness. He died while Aung San was visiting his home for summer vacation, when he was sixteen years old.
