"Free as the Wind". According to the query on the Kugou Music app, "Free Like the Wind" was written, composed and sung by Xu Wei. Excerpts of the lyrics were released on February 16, 2006: "What people fear most is the strangeness after passion, the indifference after ambiguity, seriousness The pain after trust, the indifference after tenderness, only the tenderness that is lost is the tenderest. I have loved without regrets in this life, why should I care too much about the ending."
