宋璟
In 704, Wei Chengqing was made "Fengge Shilang" (鳳閣侍郎), the deputy head of the legislative bureau, and he was also given the designation "Tong Fengge Luantai Pingzhangshi" (同鳳閣鸞臺平章事), making him a chancellor "de facto". As Wu Zetian did not wish to have two members of the same clan serving as chancellors simultaneously, Wei Sili, who was then chancellor as well, was made the principal of the imperial university. Meanwhile, there had been accusations against Wu Zetian's lover Zhang Changzong that he had permitted the fortuneteller Li Hongtai (李弘泰) to foretell that he had the appearance of an emperor, and Wu Zetian had Wei Chengqing, Cui Shenqing (崔神慶), and Song Jing investigate. Wei and Cui, after investigation, concluded that Li Hongtai should be prosecuted, but Zhang should not, as he had reported what Li Hongtai said to Wu Zetian. Song insisted on investigating, but to no avail, as Wu Zetian protected Zhang.
