你若生死相随我定生死相依
[nĭ ruò shēng sĭ xiāng suí wŏ dìng shēng sĭ xiāng yī]
An oath signifying utmost commitment; it echoes deep vows of 'if you stay with me through all circumstances so will I'. Represents eternal loyalty that spans beyond ordinary boundaries including possibly life and death itself within romantic or profound ties.
