项伯 / Xiang Bo

项伯 / Xiang Bo enters the wiki through Hanji 140 part 1 as 项羽’s uncle and an older Xiang-family figure after 项梁’s death. The source says he had helped Xiang Liang in the army, held the Chu office of lingyin, and remained a trusted elder whom Xiang Yu respected.

The episode introduces Xiang Bo at the moment when Xiang Yu decides to attack 刘邦 before 鸿门宴. Xiang Bo is shocked by the plan, and the available transcript immediately turns toward 张良 notifying Liu Bang, so part 1 keeps him as the opening of a pre-banquet channel.

Hanji 140 part 2 completes that channel. Xiang Bo rides by night to 霸上 because Zhang Liang had once protected him when he fled trouble at Xiapi. His initial goal is narrow: save Zhang Liang from dying with Liu Bang. Zhang Liang instead refuses to flee alone and brings the warning to Liu Bang.

Xiang Bo then becomes the bridge Liu Bang can work through. Liu Bang invites him in, treats him as an elder brother, offers wine and a marriage tie, and explains his conduct in 关中 as loyal waiting rather than rebellion. Xiang Bo is moved by the relationship performance and agrees that Liu Bang should personally come to the Hongmen camp the next morning to explain himself.

After returning to Xiang Yu’s camp, Xiang Bo argues that attacking Liu Bang would be “不义” because Liu Bang had entered Guanzhong first and made the coalition’s arrival possible. The source presents this persuasion as effective because Xiang Bo combines family authority, old battle-partnership memory, and a moral vocabulary that Xiang Yu is emotionally vulnerable to.

Hanji 141 moves Xiang Bo from mediator to physical protector. He sits with Xiang Yu in the high seat area, then recognizes the danger when 项庄 begins the sword dance under 范增’s instruction. Xiang Bo draws his own sword, dances as well, and shields 刘邦 with his body so Xiang Zhuang cannot strike.

Hanji 144 appears to preserve Xiang Bo’s post-Hongmen intermediary role under the transcript form “相国.” The episode says 张良 transfers Liu Bang’s gifts to this figure, who values friendship and has treated Liu Bang as someone under his protection since Hongmen. This page treats the passage as Xiang Bo context rather than creating a separate page, and records the role source-scoped: he remains a relationship channel through which Liu Bang seeks a more favorable practical arrangement after the Hanzhong assignment.

Hanji 144 part 2 completes the immediate payoff of that channel. Xiang Bo accepts the gift-mediated request from Zhang Liang and persuades 项羽 to let 刘邦 hold the Hanzhong-related space he needs before moving into the Han assignment. The episode again makes Xiang Bo’s political effect indirect: he does not join Liu Bang, but his private trust with Zhang Liang changes what Liu Bang can practically carry into retreat.

Key Claims

  • Xiang Bo’s authority in these sources comes from kinship, age, prior service in the Xiang camp, and his old life-debt relationship with Zhang Liang.
  • His entry makes the Hongmen crisis depend on personal channels inside a formal military confrontation.
  • Hanji 140 part 2 makes him the core “存刘派” figure: he does not defeat Fan Zeng’s strategic diagnosis, but he gives Xiang Yu a morally respectable reason to pause the attack.
  • Xiang Bo’s intervention shows how kin authority and old friendship can reroute an already-issued military order when the commander still cares about “义” and family recognition.
  • Hanji 141 shows the same “存刘” position becoming embodied action: Xiang Bo protects Liu Bang inside the banquet, not only through prior persuasion.
  • Hanji 144 extends the same relationship channel into post-settlement bargaining, though the available transcript has a noisy “相国” form.
  • Hanji 144 part 2 records the practical payoff of that channel: Liu Bang gains more room before entering Hanzhong and then uses 烧栈道 to protect the retreat.
