爷的痛你不会懂姐的伤你不会治
[yé de tòng nĭ bù huì dŏng jiĕ de shāng nĭ bù huì zhì]
'My Sorrow You Do Not Comprehend; My Wound You Cannot Heal' stresses personal emotional wounds and distress which are too unique or deep for others to fully understand or assist effectively. The tone can range from protective aloofness, frustration at being misunderstood, resignation in bearing loneliness.
