The theme song "Love You All My Life" was officially released on 13, with male and female starring Wan Siwei and Xiao Heqing singing at the conference. On the same day, the first concept poster of "Love Your Life" was released. The poster has no real scene, only a double happiness word, and there is a crease between the two happiness words. Huang Hong explained: "This poster uses the China classical wedding symbol, which represents a lifetime. This is the same idea. My wife and I got married under this symbol. We have been walking for half our lives, and my parents got married under this symbol. They have been gone all their lives. " As for the crease, starring Xiao Heqing said it was taken from the meaning of "taking pictures". "Projecting each other's love to each other is a complete love."
