旧颜迷离了谁的旧梦旧梦凄美了谁的旧颜
[jiù yán mí lí le shéi de jiù mèng jiù mèng qī mĕi le shéi de jiù yán]
Translates into something poetic like 'An old face confuses whose old dreams; old dreams make beautiful yet sad, whose old face', emphasizing reminiscence mixed with nostalgia leading to an ambiguous melancholy beauty of the past.
