Dali is a national regime with Bai nationality as the main body established in Yunnan in Song Dynasty. Two years later, in Tang Zhaozong (902), Zheng Maisi, an aristocrat of Nanzhao, destroyed Montessori's independence and changed his country name to "Great River". In 928, in the third year of the late Tang and Ming Dynasties, Yang Gan really destroyed the Zheng family, established Zhao Shanzheng, and changed the country name to "Datianxing". The Star Kingdom only existed for ten months. Yang Ganzhen abolished Zhao Zili and changed his title to "Dayining". Yang Ganzhen is "insatiable, suffering at home and abroad". In the second year of Tianfu at the end of Jin Dynasty (937), Duan Siping, with the slogan of "reducing taxes and half grain, delaying corvee for three years", joined forces with 37 resistance forces in eastern Yunnan to expel Yang Ganzhen and become king on his own, and changed his name to "Dali", that is, Duan Dali. Duan's victory lies in his policy of "reducing grain and lenient corvee" and the reform of "loosening and eliminating heavy taxes", which has been widely supported by the people.

AD 1096

(Song Zhe Zongshaosheng three years) Gao Shengtai died, and his son Gao Taiming followed his father's last words and returned to Zheng Duan's house to pay attention to his younger brother Zheng Chun. At this point, Dali is called "the country of post-Li".
