Meanwhile, though, Emperor Wenzong began to become close to a physician that Wang Shoucheng recommended, Zheng Zhu. Subsequently, at Zheng Zhu's recommendation, Li Zhongyan, a former official who had been exiled due to crimes, also became a close associate of the emperor. Li Zongyan was thereafter made a professor at the imperial university over Li Deyu's strenuous objections; they caused a rift between Li Deyu and Emperor Wenzong. Meanwhile, Wang, Li Zongyan, and Zheng Zhu, wanting to divert power from Li Deyu, had Li Zongmin recalled from Shannan West Circuit to serve again as chancellor, while sending Li Deyu to Shannan West to serve as his military governor. Li Deyu met with Emperor Wenzong and asked to stay at Chang'an, and initially Emperor Wenzong agreed, making him the minister of defense again. However, after Li Zongmin objected that Li Deyu should not be allowed to stay or go based on his own desire, Li Deyu was instead sent back to Zhexi Circuit, which was renamed Zhenhai Circuit, to serve as its military governor.
