一巴掌打醒的心
[yī bā zhăng dă xĭng de xīn]
Translated as 'a heart awoken by a slap', this nickname describes a feeling where someone was forced into awakening or realization through harsh reality or an intense event. Like a physical slap waking one up, it suggests moments when we face hard truths, which could be about relationships, life changes, or other significant awakenings.
