Many videos have the same background music, which is very popular and has a nice tone, but many people don't know what it is. Of course, because it is not a Chinese song, but an English song. This song was called pure music by Alan Walker in "Faded (Faded, Withered) Cool Dog", and of course there is a lyric version. Keep the change for those who are looking for this song. That's a faded song.
