Concubine Cheng (died 29 May 1784), of the Manchu Plain Red Banner Niohuru clan, was a consort of Qianlong Emperor.
Concubine Cheng was a member of Manchu Plain Red Banner Niohuru clan.
Lady Niohuru entered the Forbidden City as "Noble Lady Lan" (Chinese: 兰贵人; "lan" meaning "orchid") in 1757.[3] Her residence in the Forbidden City was Yongshou palace. She lived under the supervision of Consort Shu. In 1759, Lady Niohuru punished a eunuch who stole her clothes and sold them; a common practice in the Imperial Palace. The servant was exiled to Ningguta. After the incident, she was demoted to "First Class Female Attendant Lan" . In 1768, she was restored as "Noble Lady Lan".[4] In 1777, Lady Niohuru was promoted to "Concubine Cheng" (Chinese: 诚嫔; "cheng" meaning "sincere"), but the ceremony was delayed until 1779 because of the mourning period after Empress Xiaoshengxian.[5] She began to live together with Noble Lady Shun. Concubine Cheng died on 29 May 1784 during Qianlong Emperor's southern tour.[6] She was interred in Yu mausoleum in the Eastern Qing tombs.
