兄弟为手足女人为衣服
[xiōng dì wéi shŏu zú nǚ rén wéi yī fú]
Direct translation of this old saying means: 'Brothers are likened to limbs, wives are like clothes'. This phrase suggests that brothers should share a relationship of unity and closeness akin to blood ties, whereas a marriage or romantic relationship holds significance but in another way - as something that can be exchanged, replaced or appreciated differently, not to devalue it but emphasizing the unshakable foundation of fraternal relationships compared to romance.
