Mianqing was born on 17 June 1779 to second primary princess consort Zhizhuang of the First Rank, lady Niohuru.[1] Mianqing also had one biological sister, Princess of the Fourth Rank. [2]
Mianqing was talented since young and showed interest for art, especially for music. He was taught archery by his grandfather personally.[3] His talent for archery was shown off during the imperial hunt in Rehe in 1793. Mianqing killed a wild boar with only 3 arrows. Although Mianqing was injured, Qianlong Emperor was pleased having been informed about Mianqing's action and granted him three-eyed peacock feathers and yellow horse-riding jacket.[4]
Mianqing succeeded his father as Prince Zhi of the Second Rank in 1790, being barely 11 years old.[5] In 1802, prince consort Fengshenyinde described the relationship of Helin and Mianqing, largely concerning the long-lasting colligation between the clans. Alternative view of the colligation presented Heshen, commenting that before Helin died of malaria in 1796, he had been reciting the memorials to a group consisting of 15 people expressing deep grievance through "unclearly pronounced words" comparable to "slightly falling brush, song becoming crying cloud[Note 1]".[6]
Mianqing died on 27 November 1804 because of progressing effects of his injury. Jiaqing Emperor was deeply saddened by his death and therefore gave his descendants 5000 taels of silver for a funeral.[7]
Mianqing was posthumously honoured as Prince Zhi Ke of the Second Rank (質恪郡王, meaning: "talented and respectful")[8] and succeeded by his sole son, Yiqi.[9]
