菇凉的已死
[gū liáng de yĭ sĭ]
It translates into 'the mushroom girl is dead.' Mushrooms are associated with fairies in folklore, so this idiom may describe a once lively young girl now lost, suggesting she has abandoned or become disconnected from youthful innocence and dreams. The word '菇凉' which sounds similar to '姑娘'(girl) is intentionally mispronounced/misspelled for a more cute and playful vibe but here signifies her disappearance or death metaphorically.
