择城终老遇人白首
[zé chéng zhōng lăo yù rén bái shŏu]
'Choose a City to Grow Old, Meet Someone with White Hair' captures the longing or vision of choosing a city for aging and spending a long life there until old age. It also touches on the hope of meeting a significant other with whom one can age together, signifying partnership enduring into old age and sharing a journey till gray hairs show up ('encountering a white-haired person'). This signifies a deep connection meant to withstand time.
