Negotiation · 谈判
The Guiguzian negotiator treats the table as a diagnostic surface, and silence is the primary instrument. 「欲闻其声反默」 — to hear the other side's real position, go quiet after their opening and let them fill the void; uncomfortable silence reliably makes a counterpart bid against itself. What surfaces in that gap — deadlines, internal pressure, the walk-away almost named — is the actual negotiation, of which the stated position was only the cover. The discipline is rhythmic: open with a calibrated question, close into silence, and never mistake your own talking for progress.
Sales · 销售
Discovery selling is chuaimo (揣摩) with a calendar: a prospect's stated requirements are a mask, and masks slip at moments of extreme emotion — a budget shock (甚惧), a competitor's stumble, a quarter-end deadline (甚喜). 「揣情者,必以其甚喜之时」 — the real buying conversation happens there, not inside the scripted demo. The practitioner therefore times the ask to the moment the guard is down, and weighs (揣) the buyer's actual incentives — whose budget, whose fear — before naming a price. Deals close on the need revealed under pressure, not the one written in the RFP.
Intelligence · 情报
Fanying (反应) is the grammar of elicitation tradecraft. 「欲取反与」 — to take, first give: offer a deliberately wrong figure, and the counterpart's instinct to correct you surrenders the true one, a mechanism modern elicitors find far more reliable than direct questioning. 「欲高反下」 works the same way: play the student so the target performs the expert, then close into a silence the target feels obliged to fill. Every correction volunteered is intelligence the target believes he is withholding.
Leadership · 管理
Feiqian (飞箝) maps onto the management of reputations: assign a person an elevated identity in public — 「you are the one who never misses a ship date」 — and the pincer closes, because refusing the next hard deadline now means refusing the self you handed him. The mechanism is commitment-consistency: people move to align with the position they have been seen accepting. Used openly, this is how leaders build teams — the reputation precedes the behavior and pulls it upward. Used coldly, it is the manipulation the Guiguzi has always been accused of: the lock works whether or not the praise was true.
