心妄七九
[xīn wàng qī jiŭ]
This combines the word '心' (xin, meaning heart), 'wandering thoughts' (妄, implying delusional ideas or fantasies), and '七九' ('seven and nine'). Seven and nine symbolize two special numbers in Chinese culture and numerology, suggesting ups and downs but ultimately finding balance. It implies a person has many fleeting and fantastical hopes and ideas about romance and life but still manages to remain grounded.
