Fahrenheit (Chinese: 飛輪海; pinyin: Fēilúnhǎi; Jyutping: Fei1 Leon4 Hoi2; Pe̍h-ōe-jī: Hui Lûn-hái; Pha̍k-fa-sṳ: Fui Lûn-hói) was a Taiwanese boy band composed of members Calvin Chen, Jiro Wang, Wu Chun, and Aaron Yan.

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.

[2] Following Wu Chun's departure, the remaining members also went off to pursue solo projects, putting the group in an indefinite hiatus.

Fahrenheit first gained minor recognition around late 2005 when they first acted altogether in the series, KO One, was broadcast on television in Taiwan.

After Calvin Chen graduated from one of the top high schools in Taiwan, he further pursued his college education in Canada, where he completed his Master's degree in Economics at University of Victoria.

He entered a pageant-like competition called Sunshine Boyz in Vancouver and won first place with a free ticket to Taiwan and a contract with a music company.

In 2000, Jiro Wang started to work after graduating from Taiwan's Fu-Shin community college, and did part-time jobs wherever he could, such as commercial modeling.

Joseph Wu Chun was born in Brunei and is of Chinese descent (whose ancestors originally descended from Fujian province of China).

A television producer discovered him during this trip, and recommended him to play the lead male role of Tokyo Juliet, which Wu accepted.

Before Fahrenheit released their first album on 28 September 2006, they gained minor attention as singers from contributing in several Taiwanese drama soundtracks.

After their first album was released, their fan base had extended to South Korea, Hong Kong, Singapore, Malaysia, Japan, Philippines, Indonesia and the rest of Southeast Asia .

They already held two mini concerts: one in Medan, North Sumatra, Indonesia on March 31 and one in Tsim Sha Tsui, Hong Kong on April 19.

However, songs like Teachable Child (孺子可教 Ru Zi Ke Jiao) and Love's Arrived (愛到 Ai Dao) are intended for a light R&B approach.

The new album saw the four employ more advanced harmonizing techniques as well as some progression from bubblegum pop to more mature ballads, such as Ten Thousand Joys (一萬個快樂 Yi Wan Ge Kuai Le).

Often criticized for the lack of character in their music, Fahrenheit finally moved towards carving a more distinct musical style with their third album, Love You More & More (越來越愛 Yue Lai Yue Ai) which features a new maturity that is brought out by rock ballads like the main track, Lonesome Sprint (寂寞暴走 Ji Mo Bao Zou) and Stay With Me (留下來 Liu Xia Lai)， of which the latter was written by Monster, the lead guitarist of popular Taiwanese band, Mayday.

Guardian Star (守护星 Shou Hu Xing) is dedicated to all their fans for supporting them for 5 years and also the opening-theme for the drama Love Buffet .

Going On My Way (活得更像我 Huo De Geng Xiang Wo) is a combination of two Taiwanese Hokkien songs (收酒矸) and (酒矸倘卖无) in a rock style.

Their fourth album also features Very Quiet (很安静 Hen An Jing), the ending-theme of drama Momo Love (桃花小妹), Mistake (误会 Wu Hui) the ending-theme of the drama Love Buffet (爱似百汇) and Rebirth (新生 Xin Sheng) the opening-theme for the manga BLEACH (死神).

Closely tracing his popularity that It Started with a Kiss has given him, his company decided to give him the lead role for KO One as well as Calvin Chen and Aaron Yan for they were discovered around that same time.

After KO One aired, HIM International Music decided that it was time for Fahrenheit to release their first studio album to fulfill fans' requests.

[11] In light of Hana-Kimi's success, reports claimed that Selina and Wu would be acting in the sequel to It Started with a Kiss as a couple.

In a report at Liberty Times, it was confirmed that Wu would be starring in a new manga-based drama alongside Angela Chang.

Its popularity led to a slew of follow ups, including an online game as well as an original soundtrack that was promoted in numerous Asian countries.

Idol dramas aside, it was also reported in various Chinese sources that Wu will be starring in a new Hong Kong-based film with Gillian Chung of Twins.

[14] On April 27, 2007, the media announced that Alex Fong will take Wu's place in the new Hong Kong film, Bathing Beauty (出水芙蓉).

[15] On March 17, 2008, a press conference was held to announce that Wu will be filming a movie, Butterfly Lovers (武俠梁祝) with Charlene Choi, the other half of popular Hong Kong group, Twins.

Jiro Wang has finished filming GTV drama, Rolling Love (翻滾吧！蛋炒飯) and ToGetHer(愛就宅一起) with Rainie Yang and George Hu.

Wu is involved in yet another idol drama, Hot Shot (篮球火), acting alongside established artists, Show Lo and Jerry Yan.

In the year of 2010, Aaron has filmed two series: Love Buffet (愛似百匯) with Calvin both as male leads, and Gloomy Salad Days(死神少女) with Serena Fang.
