两手紧握陪你到天长十指紧扣伴你到地久
[liăng shŏu jĭn wò péi nĭ dào tiān zhăng shí zhĭ jĭn kòu bàn nĭ dào dì jiŭ]
The phrase translates to: 'Hands held tightly to stay with you forever and ten fingers locked tightly to go along with you for eternity.' This depicts unwavering commitment and promises to stand by the beloved's side through life’s length, expressing loyalty, and dedication for time immemorial.
