汉中 / Hanzhong
Hanji 959 adds a late-Han control layer before the Chu-Han route material below. 刘焉 sends 张鲁 and 张修 against Hanzhong, after which the Yizhou side blocks the 斜谷道 toward Chang’an and uses the cut road as a reason communication with the court cannot continue.
汉中 / Hanzhong enters the wiki through 《资治通鉴·周纪》51丨 楚怀王：秦小儿看舅舅如何灭了你！ as the major territorial loss after 丹阳之战. The source says 秦国 takes Hanzhong from 楚国 after defeating Chu and capturing 屈匄.
The episode’s interpretive point is that Hanzhong should have become 楚怀王’s practical recovery objective. Instead, he remains fixated on the six hundred li of 商於 that 张仪 had only promised verbally. Hanzhong therefore anchors the gap between real, newly lost territory and imagined compensation.
《资治通鉴·周纪》53丨秦惠王用张仪换地皮 uses Hanzhong as evidence of Zhang Yi’s value to 秦国. The host says Zhang Yi had recently helped Qin take six hundred li of Hanzhong, which makes his exposure in Chu especially bitter: a minister who just produced major territory can still become a 可交换功臣 in a later bargain.
Hanji 143 gives Hanzhong a Chu-Han settlement role. 项羽 assigns 刘邦 Hanzhong together with 巴蜀 and the capital 南郑, using the region to make Liu Bang Han king while keeping him away from direct 关中 rule. Hanzhong now sits inside 三秦压制 as both a title base and a constrained launch position.
Hanji 146 shows the human cost of that constrained launch position. Once Liu Bang reaches 南郑, many followers miss the eastern homeland and desert. The episode uses 韩信’s own flight and 萧何’s pursuit to show that Hanzhong can become a real base only if 退让式根据地经营 includes credible rank, ceremony, and future offensive purpose.
Hanji 147 supplies that future offensive purpose through 汉中对. Hanzhong is no longer only the place Liu Bang was pushed into by 项羽’s settlement; it becomes the analysis room from which Han Xin identifies 关中 and the Three Qin as the first breakable target.
Hanji 148-1 makes Hanzhong a launch platform rather than only a planning base. The episode says 韩信’s army reform and route design allow 刘邦 to move out from the Hanzhong confinement, strike through 陈仓, and recover the Three Qin. The later comparison with 诸葛亮 underscores that Hanzhong routes are not automatically reusable; army condition, opponent, timing, and broader situation decide whether the geography can be converted into success.
Hanji 155-1 adds Hanzhong as a famine-reception zone rather than a launch base. When 关中 famine reaches catastrophic levels, 刘邦 allows people to move toward Shu and Hanzhong, so the region becomes part of Han’s emergency demographic release valve.
