[1] – December 27, 709[2]), né Lu Qinwang (Chinese: 盧欽望), formally Duke Yuan of Rui (芮元公), was a Chinese official of the Tang dynasty and the Wu Zhou dynasty, serving several terms as chancellor during the reigns of Wu Zetian and her son Emperor Zhongzong.
[4] Doulu Qinwang had at one point served as the commandant at Yue Prefecture (越州, roughly modern Shaoxing, Zhejiang), and as of 693, during the reign of Emperor Gaozong's wife Wu Zetian, was serving as the minister of vassal affairs (司賓卿, Sibin Qing), when Wu Zetian promoted him to the post of Neishi (內史) – the head of the legislative bureau of government (鳳閣, Fengge) and a post considered one for a chancellor.
In late 694, Wu Zetian, displeased with the powerful chancellor Li Zhaode, exiled Li, and fellow chancellor Zhou Yunyuan and the assistant chief judge of the supreme court, Huangfu Wenbei (皇甫文備), then submitted articles of impeachment against Doulu and several fellow chancellors – Wei Juyuan, Du Jingjian, Su Weidao, and Lu Yuanfang – for not being able to curb Li Zhaode's power.
In 697, he was serving as the head of the household of Wu Zetian's son and crown prince Li Dan (formerly emperor), when she made him Wenchang You Xiang (文昌右相), one of the heads of the executive bureau (文昌臺, Wenchang Tai), and gave him the designation of Tong Fengge Luantai Sanpin (同鳳閣鸞臺三品), making him a chancellor de facto.
He made Doulu Qinwang a head of the executive bureau (now renamed Shangshu Sheng (尚書省)) again—now with the title changed to Puye (僕射).
[5] In 706, Doulu received the honorific title of Kaifu YItong Sansi (開府儀同三司) and assumed the additional responsibility as secretary general to Li Dan, then the Prince of Xiang.
