贾诩 / Jia Xu

Hanji 1010 gives Jia Xu’s pre-Wancheng survival calculation. After leaving Chang’an, he stays with 段煨, but reads Duan Wei’s courtesy as unstable because Duan Wei fears Jia Xu’s prestige in the army. Jia Xu therefore leaves for 张绣, judging that Zhang Xiu needs a strategist and that Duan Wei will still treat Jia Xu’s family well after the departure.

The same episode uses Jia Xu as the source’s judge of 刘表. Jia Xu advises Zhang Xiu to attach to Liu Biao and is received with guest courtesy, but later says Liu Biao’s virtues fit peaceful high office better than disorder-era achievement: he cannot read change sharply, lacks decisiveness, and is too suspicious. This extends both 安全第一政治生存 and 行势情战略评估.

贾诩 / Jia Xu enters the wiki through Hanji 1012 as the adviser whose counsel brings 张绣 into submission to 曹操. The episode says Jia Xu had left 段煨 and joined Zhang Xiu, who respected him like an elder and accepted his advice when Cao Cao’s southern campaign arrived.

Hanji 1013 then makes Jia Xu the adviser during the Wancheng crisis. After Cao Cao’s secret plan to kill Zhang Xiu leaks, the source says Jia Xu helps turn Zhang Xiu’s exposed position into a pre-emptive attack.

The plan is built on permission and timing. Zhang Xiu asks to change camp, says his route must pass through Cao Cao’s camp, and has his troops move in armor. Cao Cao accepts the explanation, allowing Zhang Xiu’s force to enter the camp posture needed for the night attack.

In this source, Jia Xu is not yet a full biographical figure. He is the strategist who sees that Cao Cao’s desire, confidence, and loose guard posture have created a usable tactical opening.

Hanji 1011 uses Jia Xu as a contrast rather than a plot actor. After 祢衡 dies from unrestrained speech inside stronger actors’ games, the host says Mi Heng could have learned Jia Xu’s “hide in seeming foolishness” survival wisdom. That makes Jia Xu a positive reference for 安全第一政治生存 before the Wancheng tactical branch begins.
