[2] When her sister, Mingin Supaya was found guilty of having sexual relationship with a commoner and was ordered to be imprisoned for violating social taboos concerning sex, her family and its servants were sent as slaves to Man Aung Yadana Wakhingone Pagoda.

On 25 April 1883, at a sayadaw's request, Supayalat set them free, but they remained under house arrest until the abdication of King Thibaw in 1885.

Pyinzi Supaya died on 18 May 1915 at the age of 54 and was buried in the Mandalay Palace enclosure (see Konbaung tombs).

[4] She accompanied Setkya Dewi whenever she traveled about the palace in the royal palanquin and was one of eleven princesses who had the right to wear ghanamattaka clothes during King Mindon's reign.

At the Rajabiseka Muddha consecration of her father in 1874, Pyinzi Supaya, wearing ghanamattaka clothes, together with her seven sisters, poured a libation on the king's head and made speeches.
