你的一生我来守护我的一生要你守护
[nĭ de yī shēng wŏ lái shŏu hù wŏ de yī shēng yào nĭ shŏu hù]
A mutual vow between two people where one promises to protect the other throughout their lifetime, and in return, seeks protection for themselves. It’s a profound expression of interdependent care and devotion over a lifetime.
