The Han family of Xianzhou in the Song Dynasty originated from Boyue. It was not one of the eminent families of the Tang. However, it was famous for scholarly learning since the middle of the Tang and eventually served the Chengde Military Commissioners, the Wangs. After Zhang Wenli destroyed the Wangs during the Late Liang, Han Guo moved and settled down at Anyang in Xianzhou. Han Qi represented the climax in the development of the Han family. He served the Renzong, Yingzong and Shenzong emperors and was a close friend of eminent scholars such as Fan Zhongyan, Fu Bi and Ouyang Xiu. After the death of the Shenzong emperor, the Hans became involved in a factional struggle which led to the decline of the family. The real disaster, however, came with the invasion of the Jin, which led to the migration of some of the Hans, who finally settled down in the Shaoxing area. Han Tuozhou, the great grandson of Han Qi, supported the Ningzong emperor to come to the throne and became Ningzong's favorite. He excluded Zhao Ruyu from power and monopolized the government. At this point, the power of the Han family reached another peak. However, after the failure of the Northern Incursion during the Kaixi period, Han Tuozhou, who was responsible for the failure, was killed. After this setback, the Hans never returned to power again. Although the Hans spread throughout the country, their Xianzhou hometown remained the center where family members congregated. The Hans maintained their social status through marriage. After Han Qi came to power, their marriage targets were limited only to a small number of eminent families. Moreover, most of the Hans became high officials under the yin protection, though a small portion obtained their positions via the civil examinations. The Hans heavily invested on education so as to pass the examinations. As family members who obtained office via the yin protection increased and their family status rose, their life style became increasingly extravagant and diminished their capabilities for social competition. The decline of the Hans became unavoidable .
