[bù lí bù qì bù lí nĭ ér qù bù dă bù nào zhĭ wèi nĭ xīn tiào]
'No Leaving, No Abandoning; I stay with you quietly, making my heart beat just for you.' This shows a commitment to a deep relationship. The promise includes being dedicated and faithful to the other party without argument or noise, silently supporting each other through ups and downs and experiencing everything together wholeheartedly.
