There were also monthly recitations of the vinaya in numerous cities throughout the realm. Regular examinations for monks were also organized, though this was a practice which had existed at least since the time of King Sinbyushin (1763–1776). If monks repeatedly failed their exams, they could be expelled from the sangha. Bodawpaya also made many donations to the Buddhist order, including regular food offerings, numerous copies of the Tipitaka and a wave of monastery and pagoda construction in the capital of Amarapura as well as the creation of animal sanctuaries (where hunting was prohibited). Bodawpaya also built numerous monasteries for learned Buddhist elders. One of the most learned scholars of this era was elder Ñāṇa, who wrote numerous works including commentaries on the "Nettipakarana", the "Jatakatthakatha" and the "Digha Nikaya."
