往伤口上撒盐你真善良
[wăng shāng kŏu shàng sā yán nĭ zhēn shàn liáng]
Translating to 'You’re so kind to sprinkle salt on my wound', this uses the metaphor of sprinkling salt into an open wound – it expresses sarcasm towards people who knowingly cause emotional pain. The phrase conveys that such individuals may act under a facade of kindness but truly add more hurt.
