Gu Mu/Gu Xi went from childhood to adolescence, from adolescence to youth, from youth to middle age, from middle age to old age. He didn't want to be absent. The helpless and absent time could only be filled with future candy. He said: "I hope I will always have her in front of me on my road, and I will always be here." She said: "He has always been here, and my world has always been here." One is the long-awaited king, and the other is a newborn calf. When they collide, they are mature and calm, childish and brisk. Perhaps they are a perfect match. Mu and Xi represent gentle love. Gu Mu/Gu Xi
