终年不遇感谢时光蹉跎终年不遇感谢时光不弃
[zhōng nián bù yù găn xiè shí guāng cuō tuó zhōng nián bù yù găn xiè shí guāng bù qì]
Translated as 'Meeting once in a blue moon and thankful to time passing,' it expresses appreciation for moments that are rare yet precious and gratefulness even though they're sparse and might bring vicissitudes.
