Four members of the Butterfly Group, JJ, Lang Lang, Wei Wei and Wen Wen, stood out from thousands of interviews. After the company's "sea election", more than a dozen candidates were eliminated, and then after collective training, examination and training, they became the first artists representing Oriental Cai Hua. The name "Butterfly Combination" represents a story of growing up and pursuing dreams. Before that, they were a group of hard-working caterpillars, expecting them to pass the test of winter and become beautiful and dazzling butterflies, and at the same time, they can also produce "butterfly effect" in pop music.
