赠你江山共我白头
[zèng nĭ jiāng shān gòng wŏ bái tóu]
'I offer you a kingdom if you will grow old alongside me,' this nickname romantically proposes eternal partnership in ruling the world together or spending lifetime side-by-side no matter their status. Here, giving away the metaphorical 'kingdom' suggests a high level of sacrifice made for love. It reflects the aspiration for everlasting loyalty and devotion despite external influences and time passing.
