After medical school, Maung undertook a one-year internship at the Mawlamyaing General Hospital. It was during this time that Maung began to realise how poor some people were and how much they had to sacrifice in order to get medical care. Many people sold their homes, property and land or animals so that a family member could receive medical assistance. But still they had to purchase their own supplies such as soap, blades and dressings if they required surgery. Equipment was old and often broken, and items such as syringes were repeatedly used.
