《资治通鉴·汉纪》314-1｜匈奴王归降，武帝为何怒杀500汉人

Summary

This 芮淇讲透资治通鉴 episode follows 浑邪王’s surrender to 汉武帝 through its domestic reception costs. Wudi seeks vehicles and borrowed horses to receive the surrendered population with credible imperial ceremony, but popular horse concealment leads him to threaten the Chang’an magistrate, while 汲黯 argues that a local official should not die for a burden the court has imposed.

The second dispute concerns more than five hundred Han merchants condemned to death after trading with the surrendered Xiongnu in Chang’an under rules against taking money or selling weapons beyond the frontier. Ji An contrasts literal punitive enforcement with the war deaths, treasury expenditure, civilian labor, and rewards already devoted to the surrender, grounding 归降接纳的内外成本冲突 in a concrete disagreement over diplomatic credibility, public burden, and contextual justice.

Key Claims

• Hunye King brings a large surrendered population into Han, and Wudi wants two ten-thousand vehicles for reception and transport.
• After prolonged war leaves the treasury strained, the court seeks horses from the population; some households hide their animals rather than lend them.
• Wudi treats the shortage as a threat to imperial sincerity and prestige and considers executing the Chang’an magistrate, but Ji An offers himself instead and the magistrate survives.
• Ji An argues that a surrendered subordinate should not be honored by exhausting state resources and compelling Han civilians to serve the newcomers.
• The episode says Han rules prohibited selling weapons to foreigners at the frontier or carrying money beyond it; more than five hundred merchants who traded with the surrendered Xiongnu in Chang’an were condemned to death.
• Ji An argues that ordinary merchants could not reasonably understand local Chang’an trade as illicit export beyond the frontier and that rigid application of the rule sacrifices the people the state should protect.
• Wudi does not answer the substance of the second remonstrance, later calls Ji An’s words nonsense, and Ji is removed from office after a minor offense and an amnesty.

Key Quotes

“知善不举，闻恶无言。” - the episode’s formula for why Ji An treats silence in the face of wrongdoing as culpable.

“护其叶而伤其枝。” - Ji An’s attributed image for protecting a narrow rule while harming the state’s own people.

Connections

• 汲黯 - twice challenges Wudi, first over the threatened magistrate and then over the merchants’ death sentences.
• 浑邪王 - surrendered Xiongnu ruler whose reception, rewards, followers, and trade generate the two disputes.
• 汉武帝 - ruler balancing surrender credibility and imperial prestige against material and legal costs imposed at home.
• 匈奴 - opponent whose war with Han forms the fiscal, emotional, and legal background to the surrender.
• 归降接纳的内外成本冲突 - synthesis of the tension between external incorporation and internal legitimacy.
• 帝王功业代价核算 - adjacent frame because Ji An counts war deaths, money, labor, and forgone compensation alongside the strategic value of surrender.
• 法律繁密与裁量权力 - related legal problem in which subjects cannot reliably know how officials will apply punitive rules.

Contradictions

• No settled contradiction with existing wiki content was found. The episode adds an earlier Ji An confrontation consistent with Hanji 318 and 333’s profile of public-purpose remonstrance.
• Outcome caution: the title says Wudi “怒杀” five hundred Han people, while the body most clearly says more than five hundred merchants were sentenced to death and then uses rhetorical language of “诛杀/屠杀.” This note does not independently establish that every sentence was carried out.
• Legal-scope caution: the exact statute, whether it covered money, weapons, all goods, or trade with surrendered people already in Chang’an, and the officials’ legal reasoning require primary-text comparison.
• The source is a compact structured summary rather than a verbatim transcript or primary-source study. The two-ten-thousand-vehicle request, exact merchant total, war cost, population and reward scale, dialogue, chronology, Wudi’s motives, Ji An’s causal role in saving the magistrate, and the link between his later minor offense and prior remonstrance remain episode-attributed.
