Sitt Nyein Aye came from a small village, near Nyaung-U Township in Upper Myanmar.Christina Fink, Living silence: Burma under military rule. Zed Books, 2001. . Page 208. He was born Sein Aye () to Daw Than Swe and U Tun Pe. His parents were farmers with no money for education. Monks in the village monastery provided the resources needed for him to attend high school. He secretly studied modern art but this was frowned upon by his teachers, being dubbed "mad art". He failed to achieve the top prize that would have allowed him to study abroad. Instead, he lived on the streets and sold artworks to passers-by.
