Wang Bo
After Emperor Muzong died in 824 and was succeeded by his son Emperor Jingzong, Wang Bo was relieved of his duties as director of salt and iron monopolies, but remained as the military governor of Huainan. He was also given the honorific title of "Yinqing Guanglu Daifu" () and made acting "Sikong" (司空, one of the Three Excellencies). At that time, the eunuch Wang Shoucheng was very powerful, and Wang Bo sent various treasures to Wang Shoucheng to ingratiate Wang Shoucheng. Wang Shoucheng thus recommended Wang Bo to Emperor Jingzong. When Emperor Jingzong brought this up at an imperial gathering, various advisorial officials, including Dugu Lang (), Zhang Zhongfang (), Kong Minxing (), Liu Gongquan, Song Shenxi, Wei Renshi (), Liu Dunru (), Li Jingrang (), and Xue Tinglao (), argued that Wang Bo was evil. Despite all the opposition, however, Wang Bo was again made the director of salt and iron monopolies in 825. It was said that Wang Bo, once he was the director again, was interested in ingratiating the emperor by submitting "surpluses" even though the regular revenues were lacking. However, he was credited for dredging the canals within Huainan's capital Yang Prefecture to allow proper shipment of supplies. His successors were able to rely on the canals that he dredged.
