择一城终老得一人白首
[zé yī chéng zhōng lăo dé yī rén bái shŏu]
Translating to 'Choose one city to grow old in, and find one person to grow old with', this expresses a yearning for stability, a long-term commitment, and contentment, whether it be geographical or in terms of relationships. It reflects the ideal of settling down in a chosen place, finding love, building a future, and living out life happily.
