5566 was a Taiwanese boy band, formed under Taiwanese music company, J-Star. The name is derived from their original five members (Zax Wang, Jason Hsu, Sam Wang, Rio Peng and band leader Tony Sun), working in six entertainment fields (singing, movies and dramas, hosting, modelling, commercials, and dancing). Over the course of their career, they have starred in three idol dramas: My MVP Valentine, Westside Story, and Mr. Fighting. They have also released four albums: 1st Album, Boyfriend, Long Time No See, and Bravo; two compilation albums: C'est Si Bon Greatest Hits, I Love 56 - Re-emerging Legends: 5 Years Greatest Hits; and taken part in four OSTs: My MVP Valentine OST, Westside Story soundtrack, Mr. Fighting OST, and Ying Ye 3 Jia 1. 5566 disbanded in 2008, but occasionally reunited in 2014, 2016 and 2019. Grouping 5566 not only work together as a group, but also individually. For instance, Sam Wang is famous for his appearances in many TV series as well as his membership in another company's band called 183 Club, which effectively makes him the busiest 5566 member; Tony Sun and Zax Wang often have dramas to shoot; while Jason Hsu has been featured in many local promotional campaigns. Zax Wang and Jason Hsu are also hosts of SETTV's entertainment show, Showbiz (完全娛樂 / Wan Quan Yu Le) (2002–2011). 5566 as a group has hosted TTV's Young Guns (少年特攻隊 / Shao Nian Te Gong Dui) (2002–2007) and CTS's Dou Zhen Ju Le Bu (鬥陣俱樂部) (2004–2005). Additionally, leader Tony Sun is also known to take part in a lot of the behind-the-scenes work at Jungiery. History Pre-debut Tony Sun has gained much solo experience by releasing several well-received albums in the Taiwanese dialect in the 1990s; he even gained the title of the "Taiwanese little champion". However, his popularity waned when he had to fulfill his mandatory military service. Sun was signed under Jungiery since his earlier days; this was how he used his connection with the company to secure the second part of his career. Zax Wang was a member of short-lived boyband POSTM3N. After the group disbanded, he was planning to start a cellphone shop with a colleague when Sun De Rong, Jungiery's head, contacted him. Wang took up the deal. Sam Wang was a national soccer player and a model before signing with Jungiery. He is also a member of another Jungiery boyband 183 Club.
