Political Choices in the Early Southern Song: The Deep Significance Behind "Returning to Lin'an"

Brief Introduction

"Returning to Lin'an" was one of the most controversial political decisions of the early Southern Song dynasty (specifically during the Shaoxing era). At the time, Emperor Gaozong of Song (Zhao Gou) had established a temporary court ("traveling capital") in Jiankang (present-day Nanjing). The court engaged in intense debates over whether to relocate back to the former capital of Lin'an (present-day Hangzhou). This decision was not merely about choosing a new location for the temporary court; it profoundly influenced the initial military-political landscape of the Southern Song, the strategy for resisting the Jin, and the relationship between the emperor and his ministers.

Core Knowledge Points

1. Defining the Concepts
Huiluan (Return of the Emperor): Refers to the emperor returning from a temporary residence to the capital city. Because the Jin troops had advanced south, the Emperor had not returned to Kaifeng for a long time, so the temporary residence was called the "Traveling Capital" (Xingzai*). Although returning from Jiankang to Lin'an was not a return to Kaifeng, in the context of that era, it was often viewed as a symbol of "stability."
* Jiankang vs. Lin'an: Jiankang (Nanjing) possessed advantageous defensive geography and was close to the front lines, making it suitable for military deployment. Lin'an (Hangzhou), located in the secure southeast, was conducive to the leisure of the imperial family and drew economic support from the wealthy Jiangnan region, but it had weaker military defenses and was far from the front lines.

2. The Political Chess Game Between Zhang Jun and Qin Hui
* Zhang Jun's Argument: As a core figure among the "pro-war" faction in the Southern Song, Zhang Jun advocated staying in Jiankang. He recognized that Jiankang was geographically closer to the north, facilitating the mobilization of troops and coordination with loyalist forces in the Central Plains. Maintaining this "northward gaze" was crucial for preserving the morale for counter-offensives.
* Qin Hui's Position: Qin Hui opposed returning to Lin'an, which actually aligned with Emperor Gaozong's mindset of seeking safety and avoiding danger. However, historical records often present it as Emperor Gaozong ultimately deciding to return to Lin'an, with Qin Hui playing a role in either instigating or tacitly permitting this decision. Qin Hui and the "pro-peace" faction feared that Jiankang held too much military power; they advocated weakening the authority of frontline generals and shifting the focus to Jiangnan to facilitate the implementation of a peace negotiation route.

3. Political Consequences of the Decision
The move to Lin'an marked a shift for the Southern Song court from a "wartime system" to a "peacetime system." While superficially it was a capital relocation, in substance, it involved using physical displacement to distance the court from the front lines, suppress pro-war forces, and lay the political foundation for the subsequent Shaoxing Peace Treaty.

Connection to Xuzizhi Tongjian

In the Xuzizhi Tongjian (Continued Comprehensive Mirror for Aid in Governance) written by Li Xinchuan, records regarding the "Return" are primarily distributed in the entries for Shaoxing years 4 to Shaoxing year 7 (1134–1137 CE).

1. The Debate in Shaoxing Year 4: The text records that in the 4th year of Shaoxing, Gaozong was still stationed in Jiankang. At this time, the threat from the Jin army remained, and lively discussions within the court concerned "rectifying titles" (referring to the status of the capital) and the "Traveling Capital." Officials like Zhang Jun submitted multiple memorials emphasizing Jiankang's strategic position as a hub on the "upper Yangtze River," arguing that the court should not easily move away from it.
2. The Relocation in Shaoxing Year 7: The Xuzizhi Tongjian explicitly states that in the second month of Shaoxing year 7, Gaozong finally decided to move from Jiankang to Lin'an. The book depicts the divergences among court officials by recording the imperial edicts and memorials of that time. For instance, it mentions that Zhang Jun and others attempted to detain the emperor by arguing that "since the imperial capital has not yet been recovered, one cannot lightly leave," but Gaozong insisted on moving south, citing the need to "avoid the spearhead and arrows" and "stabilize the state."
3. Qin Hui's Role: In the relevant entries, although Qin Hui was not a public opponent of the move, he indirectly supported Gaozong's decision to move south by controlling court affairs and suppressing the pro-war faction (as seen in the background of the later persecution of Yue Fei). Li Xinchuan, in his commentary or quotes, often regarded this move as a key node in the formal establishment of the Song dynasty's "isolated stability" (pian'an) situation, implying a strategic turn from active northern counter-offensives to passive defense.

Conclusion

"Returning to Lin'an" appears to be a simple change of location, but it is actually a microcosm of the political route struggles in the early Southern Song. By combining it with records from the Xuzizhi Tongjian, we can clearly see that behind this decision lay a complex balancing of pro-war vs. pro-peace stances, centralization of power vs. local military authority, and the security of imperial power vs. national defense needs.
