Zong Chuke
Meanwhile, though, under a plan drafted by Emperor Zhongzong's sister Princess Taiping and concubine Consort Shangguan Wan'er, Emperor Zhongzong's son by another concubine, Li Chongmao would be named emperor. Empress Wei would serve as empress dowager and regent, while Emperor Zhongzong's younger brother Li Dan the Prince of Xiang, himself a former emperor, would serve as coregent; Consort Shangguan subsequently formalized this in a will she drafted posthumously for Emperor Zhongzong. Wei Wen and another chancellor, Zong Chuke, however, opposed this plan on the grounds that this would require her and Li Dan to frequently confer, which violated Confucian principles that a brother-in-law and a sister-in-law should not converse with each other. Under Zong's and Wei Wen's insistence, the other chancellors did not dare to oppose their will, and Li Dan was not made coregent. Li Chongmao soon took the throne (as Emperor Shang), with Empress Wei serving as empress dowager and regent.
