【不打不成相识】〖bù d bù xing shí〗[Friends are often made after a fight; From an exchange of blows friendship grows; No acquaintance is made without a fight; No discord, no concord]

不期而遇结天缘，

打定主意珠璧联。

不敢自专撰携手，

成龙配套著诗典。

相濡以沫秀恩爱，

识礼知书子孙贤。

指经过交手，彼此了解，结交起来就更投合。Refers after fight, understand each other, make friends with become more compatible.同：不打不相识。
