Yuanhong and Du Xian, and Yuan's inabilities to moderate them, Emperor Xuanzong removed all three from chancellor positions, replacing them with Yuwen and Pei Guangting—with Yuwen given the position of Huangmen Shilang (黃門侍郎), the deputy head of the examination bureau of government (門下省, Menxia Sheng), and given the de facto chancellor designation of Tong Zhongshu Menxia Pingzhangshi (同中書門下平章事). It was said that Yuwen tried to further increase revenues by establish special offices, which caused the previously commissioned officials to have much less responsibilities. It was further said that Yuwen was intelligent and capable in increasing revenues, drawing Emperor Xuanzong's favor, but was frivolous, talkative, and nepotistic, once commenting, "Let me sit on this seat for a few months, and the realm will have no troubles."

He demoted Yuwen to be the prefect of Ru Prefecture (汝州, roughly modern Zhumadian, Henan) -- after serving 100 days as chancellor. However, after Yuwen's removal, it was said that revenues decreased sharply, and Emperor Xuanzong questioned Pei Guangting and other officials who had criticized Yuwen, "You all claim that Yuwen Rong is evil, and I have removed him. Now, what should we do if there is not enough money in the treasury? What are you here for?" Pei and the other officials were fearful and unable to answer, but Emperor Xuanzong did not punish them.
