It doesn't matter if you are late, don't ask how to answer it.

It doesn't matter if you are late, don't ask, don't turn over: don't be prosperous between lovers, don't sigh the world of cool thin, and remain innocent after years of vicissitudes. It means that no matter how the world and people's hearts change, no matter how the years change, yesterday's hair turned white, today's beauty turned yellow, and there is an emotion that remains unchanged.
