I. Royal Migration: Establishment of Nanwai Zongzheng Si and Political Reshaping

At the beginning of the Southern Song, the southward migration of the Zhao Song imperial clan not only altered Quanzhou’s social fabric but also propelled the city to the forefront of national strategy.

1.1 Strategic Relocation from Yangzhou to Quanzhou

According to the Quanzhou Establishment Records, in 1129 AD (the 3rd year of Jianyan), facing the Jin military advance, the “Nanwai Zongzheng Si”—originally established in Luoyang and later moved to Yangzhou—was forced to migrate further south. By 1130 AD (the 4th year of Jianyan), the office was officially settled within the Pingshui Gate of Quanzhou, with Zhao Shiqian, the Grand Master, personally overseeing the affairs of the imperial descendants. The initial scale of this migration was substantial. Records indicate that the first group included over 330 imperial clan members. Over the following decades, thanks to Quanzhou’s stability and prosperity, the royal population surged. By the end of the Shaoxing era (1162 AD), the number of registered imperial clan members had grown to over 2,300, making Quanzhou the second-largest royal center after the capital, Lin’an (Hangzhou).

1.2 Administrative Structure and Authority of the Zongzheng Si

The Nanwai Zongzheng Si was not merely a community management office; it was a special government bureau with independent judicial, educational, and sacrificial powers. According to the official lists in the Wanli Quanzhou Prefecture Chronicles, the office was staffed by core officials such as Superintendents and Administrators, with a total staff exceeding 15 resident officials. In 1170 AD (the 6th year of Qiandao), to handle the growing royal population, the imperial court further standardized the office’s functions, tasking it not only with genealogies (Jade Tablets) but also with organizing the imperial descendant examinations. These policies ensured that while royals enjoyed privileges like tax and labor exemptions, they were also integrated into the national civil service via the imperial examination system.

II. The Ten Palaces: Architectural Scale and Spatial Layout of the Royal Community

The influx of royals drove the rise of high-level architecture within Quanzhou, creating a unique “royal residential belt.”

2.1 Spatial Logic of the “Ten Palaces” (Shi Zhai)

According to the Quanzhou Architectural Records, to accommodate the relocated royals, the Quanzhou government designated specific areas near Suqing Gate to build the famous “Ten Palaces”. During the Shaoxing Period (1131-1162 AD), these ten complexes were arranged along the city’s main axis, featuring exquisite interiors and the highest-grade mortise-and-tenon wooden structures of the time. Each palace covered an area of thousands of square meters. Data suggests these communities included private gardens and libraries in addition to residential spaces. Research from the Quanzhou Place Name Records reveals that modern street names like “Shizhai Lane” (Ten Palace Lane) originate from these massive 12th-century royal architectural complexes. This spatial clustering transformed the western part of Quanzhou into the most concentrated elite district of the Song Dynasty.

2.2 Archaeological Evidence of the Zongzheng Si Bureau

The administrative building of the Nanwai Zongzheng Si was itself a complex engineering feat. During the Chunyou Period (1241-1252 AD), presiding officials conducted major renovations, adding the “Suqing Hall” for ancestral worship. Between 2019 and 2020, archaeological excavations at the Nanwai Zongzheng Si site unearthed numerous architectural components marked with “Guan” (Official) and precious Longquan celadon. Excavation data confirmed the massive scale of the foundations, with pillar bases typically exceeding 0.6 meters in diameter, indicating exceptionally high architectural standards. This physical evidence, particularly the uncovering of 21 core building foundations, provides a material outline of the Southern Song royal administrative body.

III. Royal Commerce: Economic Drivers in the Maritime Silk Road

Contradicting the traditional image of idle royals, the Zhao clan living in Zayton was deeply involved in overseas trade, becoming key promoters of the great age of maritime exploration.

3.1 Shipping Investments and Trade Dividends

In 1139 AD (the 9th year of Shaoxing), the imperial court officially issued edicts allowing and encouraging imperial clan members living in Quanzhou to engage in “mutual trade” to ease the national fiscal burden. According to the Quanzhou Foreign Economic and Trade Records, many royals used their political influence to form joint ventures with foreign merchants (Fanshang). By 1170 AD (the 6th year of Qiandao), the total maritime trade revenue of Quanzhou Port reached 2 million strings of cash, a significant portion of which came from activities involving imperial clan members. This injection of “royal capital” provided a stable cash flow for the port. Data indicates that royals were involved in trading 41 major categories of precious goods, including spices and pearls.

3.2 Integration of Royal Officials and Customs Management

The most iconic case is Zhao Rukuo, an imperial descendant who served as the Superintendent of the Quanzhou Customs (Shibosi) in 1225 AD (the 1st year of Baoqing). Not only did he manage trade, but he also authored the famous Zhu Fan Zhi, recording over 50 countries and regions trading with Quanzhou at the time. During his tenure, he linked the Zongzheng Si with the Shibosi to standardize “Choujie” (tax) rates. Records show the tax rate for fine goods was set at 20% and 10% for coarse goods. These rules, established by royal members themselves, significantly enhanced the legal protection and credit rating of Zayton in international trade.

IV. Cultural Legacy: Reshaping Zayton’s Education and Scholarship

The migration of royals brought advanced central plains culture to Quanzhou, rapidly elevating it into a cultural highland of the southeast during the Southern Song.

4.1 Interaction and Competition in Education

To ensure the education of royal children, Quanzhou had established preliminary educational structures by 1109 AD (the 3rd year of Daguan), which expanded into a dedicated “Imperial School” (Zongxue) after the arrival of the Nanwai Zongzheng Si. According to the Quanzhou Educational Records, the Imperial School formed a healthy interaction with the local “Prefecture School” regarding faculty and resources. During the Jiading Period (1208-1224 AD), the number of successful candidates from Quanzhou in the imperial examinations consistently ranked among the highest in the country, with royal descendants contributing over 15% of the success rate. These data points reveal the “cultural import” effect of royal migration: they brought rare ancient texts and integrated orthodox Song rituals into the soil of Zayton through annual ceremonies.

4.2 Royal Scholarship and the Value of Local Chronicles

Imperial clan members living in Quanzhou left a rich textual heritage. Statistics from the Quanzhou Cultural Relics Records show that there are 78 extant stone inscriptions related to the Nanwai imperial clan. These records cover family sacrifices and detailed descriptions of the local landscape. Around 1250 AD (the 10th year of Chunyou), several royal literati participated in the compilation of the early Quanzhou Prefecture Chronicles, elevating the local records to a national narrative level. These digital humanities archives allow us today to cross-verify the details of Song royal life through more than 5 different versions of local records.

V. The Final Chapter and Digital Preservation: From Ruins to World Heritage

Although the imperial clan in Quanzhou suffered immense impacts during the political transitions of the early Yuan, their cultural legacy remains a vital part of global maritime civilization.

5.1 Historical Transitions and Relic Preservation

In 1276 AD (the 13th year of Zhiyuan), the fleeing Southern Song regime attempted to use royal support in Quanzhou to reclaim power, but ultimately met with tragic failure. Consequently, the buildings of the Nanwai Zongzheng Si were destroyed in the fires of war, and many royal archives were lost. However, physical destruction did not erase history. In the 1988 cultural relic survey, technicians successfully re-located the core area of the Zongzheng Si in Licheng District. The current protection zone covers 21 significant historical nodes. According to the latest digital monitoring data, ground water levels and soil stability are monitored 24/7 across 22 monitoring points to prevent natural erosion of this royal site.

5.2 World Heritage Value in Digital Humanities

In 2021, “Quanzhou: Emporium of the World in Song-Yuan China” was successfully inscribed on the UNESCO World Heritage List, with the Nanwai Zongzheng Si site as a core component. It demonstrates to the world how Song state administrative power was deeply embedded in global trade networks through royal management. From a digital humanities perspective, highlighting these precise years and trade figures not only enhances research depth but also helps readers understand that Zayton’s prosperity was not just due to merchant daring, but because an imperial clan chose to intertwine its fate with the ocean in 1130 AD.
