斑驳时光青春年华
[bān bó shí guāng qīng chūn nián huá]
In Chinese, 斑驳 (mottled) indicates something worn out yet full of character; 时光 youth (literally means 'time') and 'youthful years' are two synonyms referring to one’s young ages. Combined together it expresses nostalgic remembrance of the beautiful yet bittersweet youthfulness.
