时光爱人皆薄凉
[shí guāng ài rén jiē bó liáng]
The English interpretation could be something like 'All Loved Ones Are Cool Under The Passage Of Time.' Here's what each word means: 时光 (shiguang) stands for time, and it can imply life's long process. 爱人 (ai ren), in Chinese, refers to lover. It can also represent loved one generally. With its help we add some romantic sense. All (皆 (jie)), cool (薄凉 (boliang)): this part suggests people's emotions tend to become indifferent gradually along with the passing by time.
