In the Pagan era, donors recorded their donations in the prose form of mawgun.
However, since from the Ava era, mawguns are composed in the form of poetry rather than prose.
The oldest mawgaun in the Burmese literature industry was "Pyayson mawgun" by Shin Htwe Nyo during the reign of Thihathura I.
Only Shin Thankho composed Yadanapyaungmon Sindaw Bwe Mawgun.
Mawgun is a kind of poem which uses four syllables in each line, like the classical Burmese verse.
