Mianqing was born on 17 June 1779 to second primary princess consort Zhizhuang of the First Rank, lady Niohuru.
[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]".
[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] Mianqing was married to lady Niohuru, daughter of Helin (和琳) and niece of Heshen, infamous late Qianlong era official.
