"过河拆桥" (guò hé chāi qiáo) is an ancient Chinese idiom that vividly describes ingratitude. The imagery is powerful: you help someone cross a river by building a bridge, and once they're safely across, they destroy the bridge so no one else can use it — and so they don't have to owe you anything. In modern Chinese business culture, it's a serious accusation used to describe partners, colleagues, or even friends who betray trust after getting what they wanted.
