Laughing and crying is the most painful theme song of pure love. There are no drums and bass in the whole song, but a lot of pianos and strings are used, as if holding back tears, so I let go because I love you enough. I'll give it to you when you are free. The original starting point of this song is the emotional view of lead singer A Xin: "If I fall in love with your smile, but your smile is not because of me, then I should let go and watch you smile for others, and I will be satisfied." The song is to describe this kind of satisfaction that obviously wants to persist, but it is more bitter than looking for it. I wrote this song not because of who I thought of or what movie I saw, but because of a painting, a castle peak, a missing lover and a flying kite in A Xin's heart. A man looked at the back of his beloved and said, "Even if you could still laugh at that time, you were wet with laughter!" " I often encourage myself with a sentence in the lyrics, and the happiness of contentment makes me endure heartache. Even if it hurts, people really learn to be content and love Mayday.
