Not long ago, the expectant mother Sun Yue shot the MV of her new song "Piggy Baby" in a villa community in Beijing. Sun Yue, who is already six months pregnant, was in excellent condition at the scene. Yesterday, the MV finally made its appearance on the screen. If you had to use one word to describe the feeling after watching it, nine and a half out of ten people would exclaim: "Heartwarming!"
