Ko Lay began writing poetry in the sixth grade. While at Mandalay University, he served as a librarian of the student dormitories, and was active in the university's pen club. His first published poem,
Our Place the Golden Inwa, appeared in the August 1952 issue of the
Mandalay Myanmar Lann Zin newspaper. His poetry collection
Lann Thit Poems won the First Prize of the 1965
National Literature Award for Poetry. From 1967 through 2012, he was restricted from publishing under the country's military government due to his involvement in
pro-democracy movements. In 2014, Ko Lay received the Lifetime Award for Myanmar Literature, and in 2022, he was awarded the
Alinkar Kyawswa by the Burmese government. ==Personal life and death==
