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).

After the group disbanded, he was planning to start a cellphone shop with a colleague when Sun De Rong, Jungiery's head, contacted him.

They showcased their multiple talents in their debut interview, yet their hard work was not respected, drawing much criticism and earning them a negative nickname, "Turkey", which is still used today.

Due to a serious injury that he suffered during the filming of a variety show, Rio Peng was temporary pulled out from group activities to recover.

This holds true till today; the Westside Story soundtrack and the Top on the Forbidden City OST are the only two albums that remain unrepackaged.

When activities ended, 5566 temporarily bade farewell to their home country for overseas promotion in Southeast Asia.

This was seen on the Westside Story soundtrack album, where a song by the now-defunct bubblegum-pop group R&B and a duet between Tony Sun and Cyndi Wang were included.

After "Top on the Forbidden City" was finished, Sam Wang joined a new group called 183 Club, which fame eventually rivaled 5566 in China.

2004 is also the year in which member Jason Hsu starred in his own TV series / idol drama, In Love With A Rich Girl.

Jungiery's manager, seeming to notice this and fearing that the whole J-Star group would collapse if their main pillar fell with no backups for support, then decided to shift his attention to 183 Club.

Tony Sun and Zax Wang both went to Mainland China to film their own dramas; Sam Wang along with 183 Club starred in idol drama The Magicians of Love which aired early in the year, and released an album during the summer; Jason Hsu at first stayed in Taiwan to attend various promotional campaigns, as he was still studying.

Later on, Jason starred in the movie, My Sassy Teacher, and also went to the Philippines to play a role in the series, Captain Barbell.

In May, 5566 released a special compilation album titled I Love 56 - Re-emerging Legends: 5 Years Greatest Hits.

In February, Zax Wang co-starred with Taiwanese singer Pace Wu in the drama Shi Shen (God of Cookery).

The other three members made their appearances one after another in the later half of the summer holidays: Jason Hsu co-starred with "Prince-Frog Couple" Ming Dao and Joe Chen in idol drama Ying Ye 3 Jia 1 (Ying Ye 3+1); Tony Sun starred in the Taiwan-Mainland-Hong Kong collaboration martial arts drama The Sword and the Chess of Death; and Sam Wang starred in idol drama E Nü Ah Chu (Mean Girl A Chu).

Tony also starred in a new idol drama titled Full Count (Ai Qing, Liang Hao San Huai) during fall.

5566 also took part in the recording and music video of the official Olympics song, "Beijing Welcomes You", along with 100 other artistes from China, Hong Kong, and Taiwan.

(Other Taiwanese artistes who took part in the recording included Wang LeeHom, Jolin Tsai, Kenji Wu KeQun, Vivian Hsu, Fan WeiQi, Lin ZhiLing, etc.)

January 2014 saw the on-stage reunion of 5566 when all members, less Rio Peng, appeared as special guests at a concert of fellow Taiwanese boyband, Mayday.

[3] However, the plans were eventually scrapped, reportedly due to Sam Wang's conflicting pre-existing acting schedules that hindered his availability to commit.

[5] With their return, several offers were made to the band, including an invitation to host a new Taiwanese variety show - CTV's 飢餓遊戲 (The Hunger Games).

In February 2019, the three-member 5566 held their concert, titled "SINCE 5566", at the Taipei Arena (臺北小巨蛋), with Rio Peng joining in as the guest performer.

This album is credited for bringing fame to two Jungiery artists, Cyndi Wang and the now-defunct bubblegum pop group, R&B.
