白头偕老终不悔执子之手不相离
        
            [bái tóu xié lăo zhōng bù huĭ zhí zi zhī shŏu bù xiāng lí]
        
        
            This comes from classic Chinese literature where it means 'Growing old together till white-headed will never regret, hold hands and do not leave.' This suggests eternal loyalty and dedication to one's significant other.
