死不瞑目

nǐ fù qīn kàn dào nǐ xiàn zài de shēng huó fāng shì huì sǐ bù míng mù de

你父亲看到你现在的生活方式，会死不瞑目的。

Your father would turn in his grave to see the way you live now.

nǐ bù néng zhè me huài nà huì ràng nǐ de zǔ mǔ sǐ bù míng mù

你不能这么坏，那会让你的祖母死不瞑目。

You can't be so bad. It's to make your grandmother turn in her grave.
