We are so nostalgic, everything is changing. Why do you want to feel the meaning of the past?

It means that everything in the world develops, progresses and changes with the passage of time. Our ideological understanding and thoughts must also be constantly studied and improved with the changes of the times. You can't indulge in the previous merit books, otherwise you will be eliminated by society. In order not to be eliminated, our only way is to keep pace with the times and forge ahead.
