　　The headquarters of the chieftain's office has changed locations several times over the years, finally settling in its current site in 1851 during the first year of the Qing Dynasty’s Xianfeng era. Over three generations of chieftains, the complex underwent continuous expansion, culminating in its present grand scale by 1935 during the 24th year of the Republic of China period. The architectural layout follows the traditional Han-style administrative model, comprising four main courtyards, ten secondary courtyards, and a total of 47 buildings with 149 rooms. The entire complex covers an expansive area of 10,625 square meters, with a built-up area of 7,773 square meters. The structure is meticulously organized into distinct hierarchical levels based on the chieftain’s official rank: the Grand Hall, Second Hall, Third Hall, and Main Hall. Surrounding these central spaces are 24 ancillary side rooms, along with numerous gardens, Buddhist halls, a theater stage, a ladies’ residence, servants’ quarters, kitchens, granaries, stables, an armory, and even a prison—all seamlessly integrated into the overall design. The buildings feature a well-planned layout that clearly distinguishes between primary and secondary areas, all constructed using sturdy wooden frameworks, characterized by thick beams and massive pillars. The roofs are adorned with elegant blue dragon motifs, while intricate carvings and vibrant paintings embellish the rafters and beams, showcasing the exquisite craftsmanship of the time.

　　The head of the Nandian Tusi chieftaincy carried the surname Gong, originally hailing from Shangyuan County in Yingtian Prefecture, Nanjing. In 1301—the fifth year of the Yuan Dynasty's Dade era—they were officially granted the surname "Dao" by imperial decree, leading to their alternate name, the Dao-Gong clan. By the first year of the Republic of China, they reverted to the surname Gong, though this name has been officially used for just over four generations. During the early Ming dynasty, members of the family accompanied the army on campaigns in Yunnan and, due to their repeated military achievements, eventually rose through the ranks and settled permanently in the region. Over time, they seamlessly integrated with the local Dai ethnic culture, becoming a remarkable example of Han-Dai cultural fusion. At its peak, the former Nandian Xuanfu Office governed an expansive territory and wielded considerable power, maintaining hereditary rule for twenty-eight generations—spanning more than 500 years. As a result, the family held significant influence among the frontier Tusi chieftaincies in Yunnan.
