Cui Gong (崔珙) (died 854), formally the Duke of Anping (安平公), was an official of the Chinese Tang Dynasty, serving as a chancellor during the reign of Emperor Wuzong. Background It is not known when Cui Gong was born. He was from the "Second Boling branch" of Cui clan of Boling. Cui Gong's grandfather Cui Yi (崔意) and Cui Gong's father Cui Ting (崔頲) were served as a prefectural prefect. Cui Ting had eight sons, all of whom were considered capable and who later became Tang officials, and it was said that they were compared to the Han Dynasty official Xun Yu's father and his seven uncles, who were known as the "eight dragons." Cui Gong had the same mother as his older brother Cui Guan (崔琯), who would also have a prominent career of his own. It was said that Cui Gong passed a special imperial examinations for making prompt rulings, and subsequently served on staffs of regional governors. It was also said that he was serious in disposition and was skillful in administration. During Emperor Wenzong's reign Early in the Taihe era (827–835) of Emperor Wenzong, Cui Gong served as the prefect of Si Prefecture (泗州, in modern Huai'an, Jiangsu), and later was recalled to the capital Chang'an to serve as the minister of palace supplies (太府卿, Taifu Qing). In 833, he was commissioned at the military governor (Jiedushi) of Lingnan Circuit (嶺南, headquartered in modern Guangzhou, Guangdong) and the prefect of its capital Guang Prefecture (廣州). Before he departed, he met with Emperor Wenzong to thank the emperor for the commission. Emperor Wenzong asked him how he planned to govern the circuit, and Cui was able to respond clearly and concretely, impressing Emperor Wenzong. At that time, Gao Yu (高瑀) was the military governor of Wuning Circuit (武寧, headquartered in modern Xuzhou, Jiangsu), which was well known for its unruly and difficult-to-control soldiers. As Gao was unable to control them, Emperor Wenzong wanted someone with serious presence to govern Wuning, and he therefore decided to transfer Cui to Wuning to serve as its military governor and the prefect of its capital Xu Prefecture (徐州); Wang Maoyuan (王茂元) was sent to Lingnan instead. It was said that after Cui arrived at Wuning, he was able to draw a balance between strictness and grace, causing the Wuning people to fall into line. In 837, Cui was recalled to Chang'an
