Mianmin was born on 6 March 1797 to Yonglin's second primary consort, lady Wugiya. In 1802, Mianmin was awarded a title of the grace bulwark duke. In February 1816, he arrived late for the banquet at the
Palace of Heavenly Purity in the
Forbidden City. Prince of the Fourth Rank,
Yishao cast his bowl upon the ground and ordered him to take a place. Yonglin's attempt to report the matter via his eunuch was persecuted. In 1819, he was promoted to the prince of the fourth rank. In 1820, Mianmin inherited the
Prince Qing peerage as the prince of the second rank because the peerage has not been awarded iron-cap status. In February 1823, he was exempt from overseeing music department of the
Yonghe Temple, thus entrusting the internal affairs to Yishao. Mianmin died on 11 November 1836 and was posthumously honoured as "Prince Qingliang of the Second Rank" (庆良郡王, "qingliang" meaning "content and gentle"). As Mianmin's children died prematurely, he adopted
Mianzhi's son Yicai as a successor. == Tomb ==
