柠檬不萌芒果不盲
[níng méng bù méng máng guŏ bù máng]
'Unsweet Citrus, Non-blind Mangoes' humorously refers to the idiom where 'lemon not cute' symbolizes feeling sour but still being appealing. 'Mango not blind' might mean that although mango tastes delicious, one should stay objective. Overall, it expresses that even if things may seem harsh at first, they can have hidden pleasant qualities.
