白登之围 / Baideng Encirclement

白登之围 / Baideng Encirclement enters the wiki through Hanji 150 part 4 as the opening case for 陈平’s political method. The source says 刘邦 is trapped for seven days by 冒顿单于 and a much larger 匈奴 force, creating a frozen, resource-starved military dead end.

Hanji 177 supplies the military setup before the release. 韩王信’s 马邑 surrender opens the northern breach, Liu Bang advances after early successes, and 刘敬 warns that Xiongnu displays of weak horses and sick livestock are deliberate. Liu Bang rejects the warning, continues toward 平城 in severe winter, and is drawn to Baideng, where Modu’s cavalry surrounds the mountain and city. This makes Baideng a case of 战场信息控制, 诱敌离位, and 战场围困与断粮, not only a later Chen Ping survival story.

Hanji 178 completes the release side of the crisis. Liu Bang and his men face seven days of hunger, cold, injury, and possible discipline collapse before 陈平 reaches 阏氏 with gifts and a rival-beauty threat. The source keeps that household channel important but adds 围困开口式风险权衡: Modu’s allies Wang Huang and Zhao Li fail to arrive, Han reinforcements are moving toward Pingcheng, and Xiongnu’s likely goal is limited pressure rather than direct rule over Han territory.

Hanji 179 extends Baideng’s aftermath into policy implementation. Because Liu Bang has learned that immediate conquest of Xiongnu is too costly, 刘敬 / 楼敬 argues for a real imperial marriage, goods, and envoy work as 汉匈和亲政策. The episode therefore treats Baideng not as a closed battlefield story but as the shock that makes frontier compromise plausible even when it creates household conflict around 鲁元公主.

The episode’s interest is not the battlefield order of battle. It uses Baideng to show how Chen Ping works when direct force is unavailable: he identifies the chanyu’s favored woman as the person whose private status interest can change the outer military situation. The reported “beauty stratagem” is therefore recorded as 阴谋式政治技术 routed through relationship leverage rather than open command.

For the Chen Ping sequence, Baideng matters because it gives a high-stakes version of the same pattern later visible at court. Chen Ping survives and acts by finding the non-obvious pressure point, lowering the need for direct confrontation, and letting timing rather than heroic posture solve the immediate crisis.
