柠檬心该多酸
[níng méng xīn gāi duō suān]
'Lemon Heart – So Sour.' This implies someone who feels envious or sour like a lemon. In China, “lemon” can also connote envy, much as 'sour grapes' do in English. Hence, this username can indicate someone who admits their jealousy or bitterness in situations where others excel.
