The Historical Map of Chengdu Government Road During the Northern Song Dynasty

Map Introduction

I. Administrative Establishment and Geographical Layout

The Chengdu Prefecture Circuit served as the core of the Northern Song's Four Circuits of Chuanxia (Yizhou, Zizhou, Lizhou, and Kuizhou). Its predecessor was the Xichuan Circuit, established in 965. In 1001, to strengthen local control, the Northern Song court divided the Xichuan Circuit into the Chengdu Prefecture Circuit (administrative seat: Chengdu) and the Zizhou Circuit, marking the formal origin of the geographical name "Sichuan." Its jurisdiction extended east to Mianyang and Jianyang, west to the Qionglai Mountains, north to An County, and south to Neijiang, making it the political and economic center of the Southwest. The challenging terrain, famously described as "the difficulty of the Shu roads is harder than climbing to the blue sky," prompted the Song Dynasty to implement special governance measures, including preferential policies for the imperial examinations and unique official appointment powers.

II. Economic Prosperity and Financial Innovation

• Agriculture and Commerce: The agricultural advantages of the Chengdu Plain, known as the "Land of Abundance," were continually enhanced, with land tax revenue reaching 27 million shi, supporting an interregional grain circulation system. The number of market towns ranked among the highest nationally, functioning as distribution centers for goods like silk, tea, and salt, with Chengdu becoming the largest commercial hub in the Southwest. The textile industry was particularly prominent, with silk from places like Rongzhou becoming a significant source of government tax revenue.

• Financial Revolution: In the early Northern Song, due to the inconvenience of carrying iron coins, private "Jiaozi shops" emerged in Chengdu. In 1023, the court established the "Yizhou Jiaozi Bureau," issuing the world's first official paper money, "Jiaozi," predating Europe by over 600 years. This innovation facilitated the development of large-scale commodity trade.

III. Culture, Education, and Military Strategy

• Cultural Flourishing:

  • Special provincial-level examination policies were implemented for education. The woodblock printing industry was unparalleled nationally, with Chengdu and Meizhou printing classics like the Buddhist Canon.
  • Arts like vase flower arrangement, tea culture, and incense ceremonies were integrated into daily life, creating an urban sophistication captured by the saying "Yangzhou first, Yizhou second."
  • The Su school of Sichuan learning rose to prominence, fostering a rich academic atmosphere described as "the Study of the Yi Jing resides in Shu."

• Military Strategic Point: Passes like Jianmen formed a defensive system, serving as a strategic bulwark during the Song-Liao confrontation. The 993-995 uprising led by Wang Xiaobo and Li Shun, who captured Chengdu and established the Great Shu regime, exposed governance crises and prompted Song adjustments to taxation and military management policies in the region.

IV. Indirect Interaction with the Liao Dynasty

Although landlocked, the Chengdu Prefecture Circuit participated in Song-Liao relations through:

• Economic Links: After the 1004 peace treaty, Sichuanese silk fabrics were sent to the Liao via border markets, supporting the annual tribute payments.
• Talent Export: Officials from Sichuan participated in Liao-related diplomatic decisions.
• Cultural Influence: Classics printed in Chengdu likely reached Liao territory through diplomatic exchanges.

V. Key Historical Junctures

Summary

The historical evolution of the Northern Song Chengdu Prefecture Circuit exhibited three main characteristics:

• Economic and Cultural Pinnacle: As the core of the "Land of Abundance," its commercial innovations and cultural achievements represented the highest level of development in the Song Southwest.
• Unique Governance Model: Its relative autonomy, shaped by geographical isolation, fostered prosperity but also contained the seeds of separatist tendencies.
• Strategic Buffer Value: During the Song-Liao standoff, its economic output and military defensive role helped stabilize the dynasty.

During this period, the Chengdu Prefecture Circuit was both a "paradise under heaven" and a crucial case study for understanding Song-era regional governance and frontier interaction.
