Biography
Dynastic Succession and Consolidation of Yunnan
Geluofeng was born in 712 as the eldest son of Piluoge, ruler of the southernmost Mengshe Zhao in the Erhai basin. During the early Kaiyuan era, with the decisive backing of Emperor Xuanzong, Piluoge consolidated the fractious Six Zhao into a unified regional state, shifting the capital to Taihe City in modern Dali. From youth, Geluofeng accompanied his father on military expeditions, demonstrating strategic poise, linguistic mastery of Chinese, and reverence for Confucian statecraft. Upon Piluoge's death in 748, Geluofeng inherited the kingdom. Tang Emperor Xuanzong officially invested him as King of Yunnan and Grand Master for Thorough Counsel. During his first two years, Geluofeng faithfully dispatched tribute caravans of horses, gold, and tropical aromatics to the Tang court, educating royal princes in Chinese etiquette. ### The Outbreak of the Tianbao Wars Peace was abruptly shattered by the imperial frontier administration. Zhang Qianto, the corrupt Tang Governor of Yunnan and Commander of Yaozhou, continually extorted immense treasures from Nanzhao. When Geluofeng accompanied his royal family to pay respects at Yaozhou in 750, Zhang Qianto subjected Geluofeng's consort to lewd indignities and sent false memorials to Chang'an accusing Geluofeng of treason. Outraged by the intolerable provocation, Geluofeng mobilized Nanzhao forces in winter 750, storming Yaozhou, executing Zhang Qianto, and reclaiming ancestral frontier commanderies. This defensive counter-stroke ignited the famous Tianbao Wars. ### Annihilation of Imperial Armies at Erhai In summer 751, Tang Chancellor Yang Guozhong dispatched Jiannan Military Governor Xianyu Zhongtong with an elite army of eighty thousand men to conquer Nanzhao. Geluofeng attempted diplomatic appeasement, sending envoys with humble petitions offering full reparations and pleading for imperial restraint. Arrogantly dismissing the envoys, Xianyu Zhongtong advanced toward West Erhai. Taking advantage of tropical malaria and unfamiliar mountain defiles, Geluofeng trapped the imperial troops along the Erhai waterways. Cutting the Tang supply bridges, Nanzhao columns launched a coordinated nocturnal assault, annihilating sixty thousand imperial troops. Xianyu Zhongtong fled with a few dozen horsemen. In 752, anticipating an even larger retaliation from Chang'an, Geluofeng concluded a strategic military pact with Emperor Trisong Detsen of the Tibetan Empire (Tubo). The Tibetan sovereign conferred upon Geluofeng the golden seal of "Tsenpo Chung" ("Younger Brother of the Tsanpo") and the exalted title "Eastern Emperor." In 754, Yang Guozhong levied over seventy thousand fresh recruits under Censor Li Mi to mount a second invasion. Geluofeng adopted a strategy of scorched earth and tactical retreat, luring Li Mi deep into the narrow defiles of Tiansheng Bridge near Xiaguan. Stranded without rations, the imperial army collapsed under plague and starvation. Nanzhao and Tibetan cavalry launched a devastating pincer attack, destroying the entire imperial army; General Li Mi drowned in the river. Great Tang poet Du Fu memorialized this tragedy in his masterwork *The Ballad of the War Carts* (*Bing Che Xing*). ### The Foundation of Kunming and the Dehua Stele With Tang forces expelled and the imperial center engulfed by the An Lushan Rebellion of 755, Geluofeng expanded his territory across southwestern China and northern Southeast Asia, conquering Pyu (modern Myanmar) and pushing frontiers eastward. In 765, Geluofeng directed his heir apparent Fengjiayi to construct Tuodong City on the shores of Lake Dian, laying the urban and administrative foundation for modern Kunming. He appointed captured Tang scholar-officials, notably Zheng Hui, to high administrative posts, educating native chieftains in Chinese literature and administrative statutes. In 766, Geluofeng erected the monumental *Nanzhao Dehua Stele* outside Taihe City. Authored by Grand Councillor Zheng Hui, the nearly four-thousand-character inscription articulated the profound historical truth: Nanzhao's rebellion had been forced by Zhang Qianto's tyrannical perfidy, and the kingdom's ultimate aspiration was to return to the benevolent orbit of the Chinese sovereign. Geluofeng died in 779 at age sixty-eight. His grandson Yimouxun inherited the throne, ultimately fulfilling Geluofeng's prophecy by formally reconciling with the Tang Empire at the Mount Diancang Alliance in 794.
