Xincheng

Xincheng is the supply city where Kong Ming’s celebrated Empty Fort Stratagem turns a retreat into a reprieve. After Shu’s position collapses at Jieting, the city’s exposed stores make it the next target: Kong Ming has just five thousand men against Sima Yi’s advancing force of 150,000. He conceals the city’s occupation, sits on the wall in Daoist robes, and plays a lute; Sima Yi reads the calm scene as a trap and withdraws.

Strategic Setting

Xincheng matters because it holds the Shu army’s supplies at a moment when its defenses have been badly weakened. The immediate crisis follows Ma Su’s defeat at Jieting, where his decision to camp on a hill against Wang Ping’s advice leaves his troops without water and allows Sima Yi to seize the city. With Jieting and Lieliu lost, Kong Ming hurries to Xincheng, making the supply base the focus of the next encounter.

The imbalance there is stark: Kong Ming has only five thousand men, while Sima Yi approaches with 150,000. The city is not merely a place to shelter the retreat; its stores and the possibility of their capture make it a decisive point in the campaign. If the overwhelming Wei force takes Xincheng, the danger to the Shu army is immediate.

The Empty City Stratagem

Kong Ming orders every sign of occupation removed, including the banners, and has the inhabitants remain hidden and silent. Rather than display a force capable of resisting Sima Yi, he appears on the city wall in his customary Daoist robes, accompanied by just two boys, and plays a lute. The open gates and quiet streets complete the appearance of a city that is either undefended or concealing something more dangerous.

Sima Yi rides up and sees the incongruity: an exposed city, open gates, and Kong Ming behaving as if the approaching army posed no threat. He suspects that the composure masks an ambush and orders his much larger force to turn aside. Xincheng is thus spared immediate capture not by a visible defensive victory, but by the impression that its apparent vulnerability is itself a deception.

Narrative Significance

The episode makes Xincheng a stage on which the campaign’s material weakness and strategic resourcefulness meet. Its stores draw Kong Ming to the city after the defeat at Jieting, while the small force available to him rules out a straightforward defense. The stratagem depends on controlling what Sima Yi can see: hidden defenders, removed banners, open gates, and the conspicuous calm of the lute-player together turn uncertainty against the advancing army.

The retreat also contrasts with the losses that brought the Shu forces there. At Jieting, Ma Su’s confidence in book learning over Wang Ping’s practical advice contributes to defeat; at Xincheng, Kong Ming’s management of appearances prevents Sima Yi from exploiting that defeat at once. The city’s role is therefore brief but consequential: it is the point where a failed position becomes a test of judgment, and where hesitation induced by an empty-looking fortress protects both the supplies and the retreating army.
