你的爱有农夫山泉那么纯吗
        
            [nĭ de ài yŏu nóng fū shān quán nèi me chún ma]
        
        
            The sentence asks if their love is "As Pure As Nongfu Spring". Nongfu Spring is a popular brand of bottled water in China associated with purity and refreshment. The phrase humorously questions whether one's love is similarly pure and untainted.
