豆腐渣婚姻

Jerry-built marriage 豆腐渣婚姻 dòu fu zhā hūn yīn

A marriage defined by conflict and unhappiness, much like a jerry-built (cheaply and flimsily) project which collapses easily. Such couples don't bother to get to know each other very well before tying the knot. Problems invariably emerge leading to wider family conflicts.
