BIOGRAPHY
Biography
Family and education
Xun Gequan was a son of Yimouxun, king of Nanzhao. Historical and later compilations preserve several forms of his name, including Xun Mengcou, Xin Juequan, and Xun Wujuan. Accounts state that he studied under Zheng Hui, a Han Chinese qingpingguan official in Nanzhao. Zheng had long served as a teacher to the ruling family and was known for strict instruction. Through this education, Xun became familiar with Chinese texts and political culture.
The Cangshan covenant
In 794, Yimouxun sent Xun and senior qingpingguan officials to meet the Tang envoy Cui Zuoshi at a shrine on Cangshan. The covenant marked the restoration of relations between Nanzhao and Tang and the kingdom’s gradual withdrawal from its political and military ties with Tibet. The *Old Book of Tang* account says that Xun composed a poem when the Tang envoy departed. His participation demonstrates his role in state diplomacy and the use of Chinese literary forms at the Nanzhao court.
Accession and reign
Yimouxun died in 808, and Xun succeeded him. The following year, the Tang court sent an envoy to conduct the investiture and funeral mission, recognizing Xun as king of Nanzhao and presenting an investiture seal. During his reign, he adopted the era name Yingdao and was honored by his ministers with the title Piaoxin. He elevated Shanchan Prefecture to the status of the eastern capital and designated Yangjuemie as the western capital. He also rebuilt Chongzhen Monastery in Qujing.
Xun’s reign was brief, and the surviving record contains relatively few details about his day-to-day administration. The clearest measures concern royal titles, the era name, the arrangement of the two capitals, and the restoration of a monastery. His government continued the political framework established under Yimouxun, including a renewed relationship with Tang, while retaining Nanzhao’s own court titles and administrative system.
Death and succession
Xun died in 809, in the fourth year of Yuanhe, and received the posthumous title Xiaohuiwang. His eldest son, Quan Longsheng, succeeded him. Later genealogies also list Quan Lisheng and Quan Fengyou among his sons. Because Xun ruled for only a year, accounts of his personal policies are limited, but the two-capital arrangement and Tang’s recognition are among the clearest developments of his reign.
Major Activities
The throne and relations with Tang
Xun inherited the relationship with Tang that his father had restored. After his accession, the Tang court sent an investiture and condolence mission and granted the Yuanhe investiture seal. The ceremony formed part of the diplomatic order between Tang and Nanzhao and gave external recognition to Xun’s new rule. At the same time, Nanzhao maintained its own royal titles, era name, and administrative arrangements, reflecting its capacity for independent regional government.
The two-capital arrangement
Xun designated Shanchan as the eastern capital and Yangjuemie as the western capital. Shanchan lay in the area that later became central to Kunming’s urban development; Yangjuemie continued as a major political center in the Dali region. The arrangement connected the Dianchi basin with Nanzhao’s western core and adjusted the placement of administrative centers to the kingdom’s wider territory.
Chinese literary education
Xun’s education under Zheng Hui is reflected in records of his Chinese writing. A five-character regulated verse, “Composed with the Qingpingguan Officials at the Wind-Sheltering Terrace during the Xinghui Festival,” is preserved in the *Complete Tang Poems*. It combines a festival outing with historical reflection and praise of loyal service. The poem and the verse associated with the Cangshan meeting show how Nanzhao’s ruling elite used Chinese literary forms in diplomacy and court expression.
The verifiable points of his life are as follows: in 794 (tenth year of the Zhenyuan era, Tang) he and the Nanzhao chief ministers swore the oath of alliance with the Tang envoy Cui Zuoshi at the shrine on the Cangshan; in 808 (third year of the Yuanhe era) he succeeded after Yimouxun's death, and the Tang court prepared envoys for condolence and investiture; in 809 (fourth year of the Yuanhe era) the Tang sent Wu Shaoyi to Nanzhao for condolence and investiture, and he changed the era name to Yingdao and adopted the title Piaoxin, dying in the eleventh month of the same year. His birth year is given variously as 770, 778 and 779, and the two sources do not agree, so the information card rests on his death and regnal years while the variants for his birth year are preserved side by side.
His succession is linked to that of his son Quanlongsheng: after his death in the eleventh month of 809 his son succeeded him, and the Tang court sent envoys to Nanzhao for condolence and investiture; the Nanzhao throne then changed hands several times within a few years, one starting point of the political instability of its later period. His adoption of the title Piaoxin and of the Yingdao era name also shows Nanzhao going further in setting its own titles and chronology.
The three different birth years given for him, 770, 778 and 779, also affect later calculations of his age and of the beginning of his reign.
His part in the oath at Cangshan stands as direct testimony to the restoration of relations between Nanzhao and the Tang.

Historical Assessment
Traditional records
The *Old Book of Tang* account of Nanzhao and the *Tang Huiyao* record Xun’s education, participation in the covenant, accession, and Tang investiture. Nanzhao histories preserve his era name, royal title, and capital arrangements. These records emphasize his place in diplomatic relations and dynastic succession, as well as his literary activity.
Later assessments
Later histories generally present Xun as the successor to Yimouxun and focus on his accession, the Yingdao era name, the title Piaoxin, and the two-capital arrangement. Because his reign was short and the surviving accounts are limited, his historical image is formed mainly by these institutional measures and the poems attributed to him.
Modern scholarship
Modern studies consider Xun in relation to Nanzhao kingship, Tang investiture diplomacy, urban development in Yunnan, and Chinese-language writing by Nanzhao elites. Researchers examine how the two-capital system served territorial administration and use his poetry to study education and political expression across cultural boundaries.
