Fahrenheit was a Taiwanese boy band composed of members Calvin Chen, Jiro Wang, Wu Chun, and Aaron Yan. They were formed in 2005 by Comic International Productions and HIM International Music and GMM Grammy in Thailand. Their music is distributed by WOW Music in Hong Kong and by Pony Canyon in Japan. Fahrenheit ware often associated with their labelmate seniors S.H.E, who are also under HIM International Music.
In June 2011, Wu announced his decision to leave the group to focus on his acting career, but is open to the idea of reuniting with Fahrenheit in the future. Following Wu Chun's departure, the remaining members also went off to pursue solo projects, putting the group in an indefinite hiatus.
