榻上策二分天下 / Ta Shang Ce Bipartite Strategy

Definition

榻上策二分天下 / Ta Shang Ce Bipartite Strategy is Lu Su’s Hanji 1052 program for 孙权: accept that the Han house cannot be revived and 曹操 cannot be quickly destroyed, then hold Jiangdong, control the Yangtze corridor, and build toward a southern imperial enterprise.

Current Synthesis

The concept is source-bounded to 鲁肃’s first strategic audience with Sun Quan. It starts from hard political diagnosis rather than loyalty rhetoric: Han restoration is no longer the operative plan, and immediate destruction of Cao Cao is unrealistic. The recommended path is therefore staged: secure Jiangdong, watch for northern distraction, eliminate 黄祖, attack 刘表, occupy the Yangtze line, and only then consider the larger imperial question.

Hanji 1052 frames this as a two-part天下 strategy that precedes 诸葛亮’s later three-part logic. The page preserves that as an early strategic imagination, not as a final historical map, because the source itself notes that later Red Cliffs and three-kingdom outcomes qualify the plan.

Hanji 1082 makes the comparison explicit. It treats Lu Su’s “汉室不可复兴” as the earlier hard diagnosis and Zhuge Liang’s later “汉室可兴” as a mobilizing legitimacy script for 刘备. Both strategies begin from dynastic breakdown, but they assign different political value to restoration language and organize different regional coalitions around that judgment.

Key Claims

• The strategy begins by replacing Han-restoration rhetoric with a diagnosis of power reality.
• Jiangdong is treated as the necessary base, not merely as a refuge.
• The Yangtze corridor is the expansion axis that turns regional survival into imperial possibility.
• Huang Zu and Liu Biao define the proposed southern-central targets that would let Sun Quan control the river line.
• The plan tests Sun Quan’s talent judgment because he values Lu Su’s advice despite Zhang Zhao’s criticism.
• Later three-kingdom outcomes qualify the two-part ambition without erasing its strategic importance.
• Its contrast with the 隆中对 separates a shared diagnosis of breakdown from different public legitimacy programs.

Evidence

• Strategic premise: Hanji 1052 reports Lu Su saying that Han restoration is not practical and Cao Cao cannot be quickly destroyed.
• Jiangdong base: Hanji 1052 has Lu Su tell Sun Quan to keep Jiangdong secure and wait on changes in the wider situation.
• Yangtze expansion: Hanji 1052 names Huang Zu, Liu Biao, and Yangtze control as the staged path from regional base to larger ambition.
• Sun Quan talent judgment: Hanji 1052 says Sun Quan continues to value and reward Lu Su even after Zhang Zhao criticizes him.
• Later comparison: Hanji 1082 places Lu Su’s diagnosis beside Zhuge Liang’s later formula and calls the two plans a strategic pair behind the tripartite field.

Counterevidence & Qualifications

The strategy is not the same as the later three-kingdom settlement. Hanji 1052 treats it as an earlier two-part plan and says later events, especially Red Cliffs and the emergence of a three-part order, change the practical map. Hanji 1082’s “seven-year time difference” and “strategic double helix” are host metaphors, and its contrast does not prove Lu Su and Zhuge Liang held the private beliefs attributed to them. Nor does the source set prove that Lu Su alone created Eastern Wu strategy; Zhou Yu’s recommendation and Sun Quan’s reception remain part of the evidence.

What Changed

• Created the concept from Hanji 1052’s presentation of Lu Su’s bed-side strategy.
• Added the qualified comparison with the Longzhong Plan’s different use of Han-restoration language.

Related Concepts

• 河流走廊战略根据地 - geographic complement because Lu Su’s plan turns Yangtze control into the route from Jiangdong survival to larger ambition.
• 三分天下式制衡 - contrast because Lu Su’s source-bounded plan is framed as two-part天下 before later three-part outcomes.
• 行势情战略评估 - diagnostic relationship because the plan begins with a situation assessment rather than wishful loyalty language.
• 以贤臣为宝 - talent-use relationship because Sun Quan’s acceptance of Lu Su shows strategic counsel becoming regime capacity.
• 识人授权信任 - personnel relationship because Sun Quan must read Lu Su against Zhang Zhao’s negative evaluation.
• 继位权威整合 - succession relationship because the plan gives the young successor an outward strategic program while internal authority is still forming.
• 隆中对 - contrast because the later plan retains Han restoration as political legitimacy while organizing a tripartite coalition path.
