丢东丢西丢不了你忘这忘那忘不了你
[diū dōng diū xī diū bù le nĭ wàng zhè wàng nèi wàng bù le nĭ]
This refers to being forgetful about everything but the significant other remains unforgettable, indicating deep-seated attachment and preoccupation with the partner. It conveys that even while forgetting trivial things, the thought and feeling of love for the other cannot be easily dismissed or forgotten.
