忘东忘西忘不掉你丢三丢四丢不掉你
[wàng dōng wàng xī wàng bù diào nĭ diū sān diū sì diū bù diào nĭ]
Forget everything here and there except you. Forget items everywhere except forgetting you. This phrase repeats itself using synonyms to convey how much harder it is to forget a certain someone, compared to other objects or tasks which are easily forgone in day-to-day activities
