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.

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.

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.

Counterevidence & Qualifications

The strategy is not the same as the later three-kingdom settlement. The source explicitly 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. It also does not 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.

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.
