At the age of seven yrs he studied together with young Bodaw Payah at the Royal Ava, Monastry (Sae Daw Phongyi Kyaung). Bodaw Paya appointed him as the head of a mission to India to retrieve books and scriptures. Actually he was sent as… the spy, disguising as the persons searching for the books and scriptures. He also got the contact with few city state kings in India, some of them sent some presents and requested the Burmese Army’s help to fight back the British.U Nu was later sent again as a spy to India by Bagyidaw who succeeded Bodawpaya. King Bodawpaya (1782–1819), with the help of U Nu’s Bengal team’s information and maps managed to capture the western kingdom of Rakhine, which had been largely independent since the fall of Bagan, in 1784. Bodawpaya also managed to formally annex Manipur, a rebellion-prone protectorate, in 1813.
