失去你让我学会了珍惜拥有你让我感觉到了幸福
[shī qù nĭ ràng wŏ xué huì le zhēn xī yōng yŏu nĭ ràng wŏ găn jué dào le xìng fú]
Means ‘Losing you taught me how to cherish, having you made me feel happiness’. It represents learning to value people deeply after they’re gone but also recognizing how good it was while having them.
