Lyrics: It's you, the dancing mist and rain. Sweeping up, ripples deep in the heart of the water. I held my breath and stayed where I was. But I dare not ask you if there is a date for my return. It's me, the passionate tide of mountains and rivers. Lifting it up, Chaoyun Muyu sighed. You are out of reach, as if you are far away. I have no choice but to wait and wait for time to grow old. I think I'm the koi. The crowds are looking for you, you are like the wind, the rain, the sky and the earth. I can’t catch you and can’t pull you away. I wish I was a koi and let the whole world convey the news. I wish they all have good luck. I just want you for the rest of my life.
