After Zhuge Liang's death in 234, Jiang Wan succeeded him as regent and did well in gaining the Shu people's confidence and leading them into a post-Zhuge Liang era. During this time, he considered that the land-based route through the Qin Mountains used by Zhuge Liang during the Northern Expeditions was too difficult for navigation and transportation of supplies.

However, the Shu government rejected his plan as they thought it was too risky. In 243, due to poor health, Jiang Wan relocated from Hanzhong near the Wei–Shu border to Fu County.
