执子之手与自偕老
[zhí zi zhī shŏu yŭ zì xié lăo]
'Holding your hand to grow old together with myself.' It comes from an ancient Chinese love poem, indicating loyalty, dedication, and a promise to be with someone until the end of life. There is possibly a slight mistake; typically it's '执子之手与子偕老' (holding your hand to grow old together), reflecting a deep and enduring bond between lovers.
