Han Yi (韩亿), known as Billionhappy, was born in 1999 in Anhui, China. A musician and fashion creative currently based between Shanghai and Hangzhou, his work draws on a wide range of influences. Jay Chou's ability to blend genres shaped his view of music, while Miyavi's bold approach to performance and style left a strong mark on his artistic identity. Connections with Internet-era collectives like GothBoiClique and Drain Gang later became central, with artists such as Lil Peep, Bladee, and Ecco2k offering both comfort and inspiration. The result is a sound that combines trap, emo rock, and electronic elements into something distinctly his own. He first appeared on the public stage through The New Generation Hip-hop Project (少年说唱企划), fully aware that his music might not be understood immediately and facing the usual doubts directed at image-driven performers. By then, however, he had already released four projects and multiple singles, building a foundation as a professional artist. Tall and sharply styled, Billionhappy often leaves a strong first impression through fashion and presence. Beyond appearances, his personality is marked by humility, approachability, and a quiet sense of charisma. The same qualities shape his music, which prioritizes atmosphere and emotion over posturing, turning everyday experiences into reflective, personal narratives. With a growing catalog and expanding recognition, Billionhappy stands as part of a new generation of artists moving fluidly between rap, Internet culture, and fashion.
