旧爱不朽新爱万岁
[jiù ài bù xiŭ xīn ài wàn suì]
This phrase means 'Long live the new love, yet the old love remains undying,' implying simultaneous devotion to past and present relationships or sentiments. This can be seen as a tribute to memories that never fade away, while embracing fresh possibilities or connections, showing reverence for both time-honored emotions and those emerging now.
