Aska Yang, Diamond-Liangliang Lyrics: Liu Chang Composer: Tan Xuan Arranger: Wei Guokun Female: The night is getting colder and the flowers are falling in first frost. You looked into the distance and ran out of the twilight. You don't think about it. It's hard to forget each other. Man: How did you leave this sea heart in the past? You are still cold and far-fetched, which is an illusion. Woman: The cool night has turned into a river for you. It cares about me. M: The shallow years are full of lovers' sleeves. Woman: Cool. There was still some hatred in my last life: I hated my daughter in my last life and my temples were slightly frosty. How can I waste my time wandering because you have already returned to the light? How can you waste time wandering man: Go wandering woman: Become an adult man: It's getting hotter and hotter in my life, so I'm relieved. One is enough. On the back of Sansheng is a pair of women: on the back is a pair of men: on the water side, the cold night is a river for you to turn into spring mud to care for me. I was covered in dust and hurt my man: I was robbed of my life and I was ruined by my feelings. There was still some hatred in my last life: Liang Sansheng III suddenly had a dream and tears dried up in the years. M: If I can't recognize the memories, I will let my feelings return to dust. W: When will I see a cool breeze under the spring tree? M: The fallen petal is intentional and heartless. Don't let resentment, love and hate cool the homozygosity of that flower: I want to live my life.
