时光不老伴你长久
[shí guāng bù lăo bàn nĭ zhăng jiŭ]
This translates as 'Time remains young, and so do we' which implies that no matter how time flies by, they would keep accompanying each other. Such kind of expression always comes from a long-term relationship, it could either mean between couples or friends who have walked through a lot together over many years
