How did the Song respond to Jin pressure?

• A. By fortifying borders, forming regional alliances, and moving the center of power southward
• B. By surrendering Territory and ceasing all military projects
• C. By increasing taxes on merchants only
• D. By building a navy to invade Jin homeland

Answer: (A)

When faced with Jin pressure, the Song relied on a defensive strategy that preserved its state and resources while looking for ways to blunt the threat. Fortifying borders meant strengthening frontier defenses and garrisons to slow and deter invasions, protecting the heartland and its economic base from rapid attacks. Forming regional alliances provided a counterweight to Jin power, creating a network of partnerships and diplomacy to check expansion and buy time for consolidation in the south. Moving the center of power southward allowed the Song to anchor governance in the wealthier, more secure Yangtze region, where administration, taxation, and military reform could continue with less risk, ensuring the dynasty survived and could rebuild.

Surrendering territory and ceasing all military projects would abandon resistance and collapse from the outside in. Increasing taxes on merchants only shifts internal pressures without addressing the external threat. Building a navy to invade Jin homeland would be an aggressive gamble that did not match the available resources or the strategic situation, given Jin’s northern strength and the Song’s vulnerability after losing the north. The chosen approach—defense, diplomacy, and relocating the capital south—best fits how the Song actually adapted to Jin pressure.
