The name of this piece is also a reference to fireflies, but the feeling is more appropriate! When I entered the mountain at the end of spring, I could still see the faint glow of fireflies by the clean spring through the moonlight, and the fluttering of golden-green fireflies was very beautiful and looked very dazzling at night. There are times when the road of life is uncertain, when we can't see the road, like the night when we can't see our fingers, but if there is Yoyo in front of us, even if it is only a faint glow, we don't seem to be so afraid to move forward.
