丢三拉四丢不掉你忘东忘西忘不了你
[diū sān lā sì diū bù diào nĭ wàng dōng wàng xī wàng bù le nĭ]
The meaning of this phrase can be summarized as 'Forgetting everything but you'. It conveys the message that no matter how forgetful the person may be (losing things here and there, forgetting various matters left and right), there's only one thing that they would never be able to forget - 'you'. This can indicate a strong emotional bond and love for another person that cannot be erased easily.
