Zheng Zhu
During Emperor Muzong's reign, Wang Shoucheng became one of the two palace secretaries general ("Shumishi"). He was said to be very powerful and involved in affairs of state, such that in 823, the official Zheng Quan (鄭權) was able to beg Wang through Zheng Zhu and be made the military governor of Lingnan Circuit (嶺南, headquartered in modern Guangzhou, Guangdong). Wang was also in an alliance with the chancellor Li Fengji.
