深知你是梦才会放手痛
[shēn zhī nĭ shì mèng cái huì fàng shŏu tòng]
Translating closely, 'Only Knowing You Are A Dream Can I Let Go With Pain.' This signifies deep emotional conflict. Realizing the relationship was illusory (a dream), it was hard but essential for this person to relinquish their attachment with considerable pain. They understood that what once appeared real wasn’t tangible, leading to painful acceptance.
