重顾余温余温散尽
[zhòng gù yú wēn yú wēn sàn jĭn]
This name 'Revisiting the Lingering Warmth' conveys revisiting a past memory or experience where some residual warmth (affection, happiness) is felt again, however, the latter part means these feelings have dissipated, reflecting on the transient and evanescent nature of certain sentiments in the heart.
