唱反调

bù guǎn shì shuí tā dōu huì gēn rén jiā chàng fǎn diào

不管是谁，她都会跟人家唱反调。

She would play devil's advocate with anyone.

zuò wéi wéi nuò nuò de rén fēi cháng bù hǎo dàn zhè bù yì wèi zhe nǐ yīng shí cháng yǔ nǐ de shàng si chàng fǎn diào

做唯唯诺诺的人非常不好，但这不意味着你应时常与你的上司唱反调。

Being a yes man is bad, but that doesn't mean you should constantly disagree with your boss.
