《资治通鉴·汉纪》690丨交友不慎有多可怕？看看田戎的经历！

Summary

This 芮淇讲透资治通鉴 episode backfills Jianwu 4 / 28 CE immediately before Hanji 691 and Hanji 692. It centers on 田戎’s failed turn toward surrender after 辛臣 steals his valuables, defects to 岑彭, and sends a letter that makes the planned submission look unsafe. The wider episode links that trust failure to 吴汉’s non-assault handling of a local revolt, 傅湛’s advice to prioritize core regions before 彭宠, 盖延’s failed Lanling rescue, and 侯霸’s reconstruction of administrative precedent.

Key Claims

• 田戎 initially wants to submit after hearing of Qin Feng’s defeat, but 辛臣’s stolen treasure, defection, and invitation letter break confidence in the surrender channel.
• Tian Rong’s burned-shell divination turns uncertainty into reversal: the unfavorable crack becomes the reason to rebel and join Qin Feng before Cen Peng defeats him.
• 延岑 / Yan Cen already appears before the later Shu endgame: 邓禹 defeats him at Shunyang, after which he flees to Hanzhong and receives high office from 公孙述.
• 吴汉 handles the Gexian revolt as a governance-fault problem, refusing immediate assault, arresting the acting county head, and persuading the five local families to surrender.
• 傅湛 stops 光武帝刘秀 from personally attacking Peng Chong by arguing that closer domestic regions should be secured before a distant Yuyang campaign.
• 盖延 ignores Liu Xiu’s indirect-relief advice to attack Tan, enters Lanling after 董宪 feigns retreat, then fails to save the surrendered Ben Xiu.
• 侯霸 preserves Linhuai through the Wang Mang disorder and later helps Liu Xiu restore governing capacity by collecting scattered institutional documents and usable former laws.

Key Quotes

“舍近谋远，弃易求难” - Fu Zhan’s criticism of Liu Xiu’s proposed personal campaign.

“龟甲从中裂开” - the episode’s divination turning point in Tian Rong’s decision.

“围魏救赵” - the host’s label for Liu Xiu’s proposed attack on Tan to relieve Lanling.

Connections

• 田戎, 辛臣, 岑彭, and 归降信任崩塌 - planned surrender collapses after intermediary defection, stolen property, and suspicious communication.
• 术数俘获式决策失控, 张丰, and 田戎 - divination and a fake imperial-seal claim redirect military-political judgment.
• 延岑 / Yan Cen, 邓禹, and 公孙述 - early defeat and Hanzhong-Shu incorporation before the later Chengdu sequence.
• 吴汉, 归咎安抚式平叛, and 王梁 - Linping victory and Gexian non-assault pacification expand Wu Han’s pre-Shu profile.
• 傅湛, 彭宠, and 先内后外式战略顺序 - campaign sequencing advice redirects Liu Xiu away from a distant personal expedition.
• 耿舒, 耿况, 耿弇, and 耿国 - Geng-family action against Peng Chong and court-service signaling.
• 盖延, 董宪, and 围魏救赵 - Lanling shows a failed execution of indirect-relief logic.
• 马成 and 李宪 - the Shouchun/Lujiang branch opens a separate siege against Li Xian.
• 侯霸 and 旧制文献恢复式制度重建 - postwar state capacity depends on recovering usable administrative memory.

Contradictions

• No settled contradiction with existing wiki content was found.
• Identity normalization: this source’s 田戎 / Tian Rong is kept distinct from 田荣 / Tian Rong, the Chu-Han Qi actor. 董宪 is kept distinct from 董贤, and 李宪 is kept distinct from other Li Xian routes.
• Qin Feng, Qin Feng’s exact defeat sequence, Shunyang, Hanzhong title details, Gexian’s five families, the acting county head, Chen Jun, Zhu Hu, Liu Xi, Liu Long, Ben Xiu, Lanling/Tan geography, and exact troop deployments remain source-scoped unless later notes require standalone pages.
