伴你伴到呼吸停止伴你伴到心跳骤停
        
            [bàn nĭ bàn dào hū xī tíng zhĭ bàn nĭ bàn dào xīn tiào zhòu tíng]
        
        
            It means accompanying someone until their breathing stops and heart ceases to beat, expressing a profound level of commitment and dedication, literally vowing to stay together until death separates two people.
