The Cuan family was originally a powerful force among the Yi people. During the Three Kingdoms period, Zhuge Liang went south and adopted the policy of "using barbarians to control barbarians", and the Cuan family began to grow and develop. In the later period, the Cuan clan was the collective name for the ruling group in the South Central region. The "Cuan Longyan Stele" was erected in the second year of the Ming Dynasty (AD 458), and was unearthed in Yangqitian, Qujing, in the 43rd year of Qianlong's reign in the Qing Dynasty. The excavation of the stele shocked the epigraphy and calligraphy circles and became famous at home and abroad. Inscription: In the eighth year of Xianhe in the Eastern Jin Dynasty (AD 333), Li Xiong sent Li Shou to lead troops to capture Nanzhong. Li Shou was named "King of Jianning"; Cuan Chen was appointed as the governor of Jiaozhou; Huo Biao was appointed as the governor of Ningzhou. In the fifth year of Xiankang (AD 339), the Cuan family sent Huo Biaofu to the Jin Dynasty, and the Yi people ruled the southern area for more than 400 years.
