别等失去才懂珍惜
[bié dĕng shī qù cái dŏng zhēn xī]
This nickname 'Do Not Wait to Lose Before Learning to Treasure' reflects a common regret many people feel in life. People often fail to cherish what they have until it's gone, and this name serves as both a self-reminder or an outward reflection of one's wisdom from past experiences.
