脚踏两条船你划得真漂亮
[jiăo tà liăng tiáo chuán nĭ huà dé zhēn piāo liàng]
It's an ironic phrase which means someone is deceivingly involved in two affairs and handling the deceit in an impressive manner. The original expression 'standing on two boats with one foot each' indicates betrayal in relationships, and adding 'paddle so beautifully' mocks this behavior.
