梦太好却终会醒爱太深却终两散
[mèng tài hăo què zhōng huì xĭng ài tài shēn què zhōng liăng sàn]
'The dream is beautiful, but ultimately you must wake up; Love was so deep, yet finally we part ways.' This reflects a sad realization about how wonderful things cannot last forever, be it a fantasy in a dream or deep-seated affection.
