The song "Butterfly Spring" was originally sung by Peng Qing from Communication University of China. "Border of the Butterfly Spring" Lyricist: Peng Qing Composer: Peng Qing Original singer: Peng Qing Lyrics: I saw all the flowers blooming, and there was a faint voice singing. It looked like its most brilliant smile, and it was brighter than the sun, and the clear water was rippling. The spring, what a beautiful little village. I saw the faint fluttering clouds imprinted on the flower clothes. I sang the songs sung by my mother. The peonies were embroidered on the golden plaque. I hummed the tunes my father sang. The cattle and sheep were grazing on the green grassland. Surrounding the butterflies flapping their silver wings, chasing back the distant ancient time, chanting about freedom and brave birds, singing non-stop. The gently beating water splash on the leaves occasionally wets the tips of my hair. Such a wonderful little transformation in the world under the sun. I am singing the ballads my mother sang. The peonies are embroidered on the golden plaque. I am humming the tunes my father has hummed. On the green grassland, cattle and sheep are grazing, surrounded by butterflies flapping their silver wings. Looking back at the distant ancient time, I am singing about freedom and bravery. The birds kept singing and kept singing. I sang the songs my mother sang. The peonies were embroidered on the golden plaque. I hummed the tunes my father had hummed. On the green grassland, the cattle and sheep were surrounded by the butterflies flapping their silver wings. I chased them back. The distant and ancient time sings about the free and brave bird. It keeps singing. Surrounding the butterfly flapping its silver wings. Looking back. The distant and ancient time sings about the free and brave bird. It keeps singing. It keeps singing. The leaves are soft. The beating water occasionally wetted my hair, which transformed into a wonderful little human being under the sun.
