《资治通鉴·周纪》34丨秦国总理如何玩转六国

Summary

This 芮淇讲透资治通鉴 episode continues the sequel promised by Zhouji 33: instead of remaining checked behind 函谷关, 秦国 is again active from 332 to 328 BCE. It follows 犀首公孙衍 disrupting the 合纵 line, Qin’s repeated territorial pressure on 魏国, and 张仪’s return-Puyang maneuver. The core reading is that Qin’s expansion combines force, alliance disruption, hostage signaling, and strategic concession diplomacy, not simple battlefield conquest.

Key Claims

• In 332 BCE, Qin uses 犀首公孙衍 to draw 齐国 and Wei into an anti-赵国 arrangement, helping break the still-fragile hezong order.
• 赵肃侯 blames 苏秦 after the diplomatic failure, and Su Qin leaves Zhao for Yan while saying he will take revenge on Qi.
• Zhao’s flooding of the Yellow River dikes forces the Qi-Wei army to withdraw, but the same year Wei still seeks peace with Qin by ceding 殷晋.
• Qin keeps pressing Wei after that settlement: it surrounds 焦邑 and 曲沃 in 330 BCE, receives 少梁 and 河西 land, and then takes Fenyin, Pishi, and Jiaoyi in 329 BCE.
• The 329 BCE succession and coup notices widen the map: 楚怀王 succeeds 楚威王, while 宋君偃 overthrows 宋剔成 and sends him into exile in Qi.
• In 328 BCE, Qin captures 蒲阳 from Wei under Gongzi Hua and Zhang Yi, but Zhang Yi advises 秦惠文王 to return the city and send a Qin prince as hostage.
• Zhang Yi then turns Qin’s apparent generosity into pressure on 魏惠王, and Wei responds by yielding 上郡’s fifteen counties to Qin.
• The episode treats Zhang Yi’s success as “欲擒故纵”: a high-risk bet in which a small concession, backed by Qin’s stronger position, extracts a much larger territorial gain.
• Zhang Yi’s reward is ministerial elevation in Qin, making Zhouji 34 the point where the strategist previewed in earlier 纵横家外交 pages becomes a visible Qin decision-maker.
• Qin’s later return of Jiaoyi and Quwo becomes the episode’s closing problem, suggesting that Qin’s strategy is not reducible to keeping every captured place immediately.

Key Quotes

“欲擒故纵” - the episode’s phrase for Zhang Yi’s Puyang-for-Shangjun maneuver.

“秦国对魏国很宽厚” - Zhang Yi’s rhetorical frame for turning Qin’s returned territory into Wei’s obligation to reciprocate.

“为什么归还焦邑、曲沃” - the closing question that turns Qin’s apparent leniency into the next strategic puzzle.

Connections

• 张仪, 秦惠文王, 蒲阳, 上郡, and 欲擒故纵式让利外交 - the episode’s main diplomatic maneuver.
• 秦国, 魏国, 殷晋, 焦邑, 曲沃, 少梁, and 河西 - Qin-Wei territorial pressure from 332 to 328 BCE.
• 苏秦, 赵肃侯, 合纵, 连横, and 犀首公孙衍 - alliance collapse and the rival persuader field.
• 楚国, 楚威王, 楚怀王, 宋国, 宋剔成, 宋君偃, 齐国, and 燕国 - succession, coup, exile, and side-front notices.
• 《资治通鉴》, 周显王, 函谷关, and 编年错位 - annalistic frame and source-critical sequel to the Shiji fifteen-year claim.

Contradictions

• This episode turns the Zhouji 33 warning into a concrete source tension: 《史记》’s claim that Qin troops did not dare leave 函谷关 for fifteen years after Su Qin’s 合纵 success conflicts with the 《资治通鉴》 sequence summarized here, where Qin disrupts alliances, attacks Wei, takes territory, and elevates Zhang Yi within only a few years. The wiki should keep this as a source-tradition conflict rather than flattening either account into a single clean chronology.
