Cherry blossoms at fingertips enter the world. Whose joke is the lyrics of which song?

I want to ask whose youth is the lyrics of which song when cherry blossoms come into the world at your fingertips. Whose youth is the cherry blossom at the fingertips? It is the lyrics in Wen Yixin's "Flowers bloom all the way", because the lyrics are to escort the dream at that time to resist the wind and sand. The cherry blossom at the fingertips is like a poem about whose youth, and crazy love is accompanied by elegance. As a result, the cherry blossoms at the fingertips entered the youthful world of the lyrics in Wen Yixin's Flowers Along the Way.
