Share a common fate; close interdependent relations where if one falls, the other suffers.
How it's used
This idiom is a classic four-character expression used to describe a relationship where two parties are so closely linked that the failure of one inevitably leads to the downfall of the other. While it originates from historical political strategy, it is frequently applied in modern contexts to business partnerships, family ties, or even team dynamics. It carries a serious tone, often used to warn someone that acting against an ally is ultimately self-destructive.
