我非柠檬哪来的心酸我非西瓜哪来的甜美
[wŏ fēi níng méng nă lái de xīn suān wŏ fēi xī guā nă lái de tián mĕi]
'Wo Fei Ning Meng Na Lai Xin Suan? Wo Fei Xi Gua, Na Lai Tian Mei?' is like saying 'If I Were Not Lemon, Where Would Bitterness Come From? If I Were Not Watermelon, Which Sweet Would There Be?', this phrase reflects contrasting characteristics: some people experience sadness and sweetness differently based on situations, sometimes sarcastically acknowledging complex emotions inside oneself.
