Yongzhang (永璋; 15 July 1735 – 26 August 1760) was the Qianlong Emperor's third son by Consort Chun.
[1] Yongzhang was not particularly excellent in horse riding because of lung disease, typical for his sister and mother.
[2] When Yongzhang was critically ill at the age of 15, Qianlong Emperor ordered lamas to pray for him.
[5] In 1759, the Imperial Noble Consort Chunhui fell sick in the Chengde Mountain Resort.
Although Yongzhang was married to lady Borjigin, daughter of Heshuo Princess Shushen and Guanyinbao,[7] he was unable to have male heirs because his sole son died prematurely and his daughter had no rights to inherit the peerage because of her marriage.
