地老天荒太长朝花夕拾太短
[dì lăo tiān huāng tài zhăng cháo huā xī shí tài duăn]
'Time seems too long to wait for till Doomsday while cherishing past moments briefly in memories is far too short.' This reflects a melancholic appreciation of how fleeting the precious times with a loved one are when compared against the vast expanse of time.
