曾经我们擦肩而过现在我们远隔千里
[céng jīng wŏ men cā jiān ér guò xiàn zài wŏ men yuăn gé qiān lĭ]
'We once passed each other on the street, now we're separated by thousands of miles'. Reflecting on missed opportunities in past encounters which led to a vast distance between two people both physically and perhaps emotionally.
