饥附饱扬 / Ji Fu Bao Yang

饥附饱扬 / Ji Fu Bao Yang enters the wiki through Hanji 1018 as 陈登’s reported description of how 曹操 judges 吕布. The phrase names a dependency pattern: when hungry or constrained, a person attaches; once fed or secure, that person lifts off and leaves.

The concept is not a general claim that all alliance behavior is selfish. Its wiki use is narrower: it marks a leader whose cooperation may depend on continued need rather than trust, institutional commitment, or shared durable interest. In the source, this lets Chen Deng turn Cao Cao’s suspicion into a face-saving explanation Lü Bu can accept.

Key Claims

  • Need can create temporary obedience without creating durable loyalty.
  • Feeding, rewarding, or empowering a volatile actor can reduce dependency and increase exit risk.
  • A mediator can make a hostile judgment usable by translating it into the target’s vanity and self-protection language.
  • The pattern belongs near 利益结构式联盟脆弱性 because both ask whether apparent cooperation rests on durable interests.
