I've Seen Old Snow and New Spring

There are countless avenues in the world, and you can reach the top of them all. But there is no eternal life in this world. They have seen the most glorious era and have seen away countless old friends. I found out later. They are not the last remnants of the old days. But the first dawn of a new era. I'm lucky enough to have met them. I have also seen old snow and new spring.
