Malaysian singer and actress

Queenzy Cheng Koon Si (Chinese: 庄群施; pinyin: Zhuāng Qúnshī; Pe̍h-ōe-jī: Chng Kûn-si; 26 February 1986 – 28 November 2023) was a Malaysian actress and singer, the member of music group M-Girls.
Biography
Queenzy Cheng was born on 26 February 1986. Her musical career began when she was five, performing solo in a relative's wedding reception. She gradually transformed into an artiste, launching her debut at the age of eight. Famous for releasing Chinese New Year albums over the last two decades, Queenzy also performed across other genres, from classical music to musical theatre and pop.
Following the success of her albums, Queenzy collectively formed M-Girls (四个女生) in 2001 with three other emerging artistes: Angeline Khoo, Cass Chin and Crystal Ong. The M-Girls' debut album and subsequent releases won multiple awards, and M-Girls was quickly dubbed the S.H.E of Malaysia. Their albums were not only the fastest-selling albums in the history of Malaysian Chinese New Year albums, but also in the Asian region. To date, M-Girls have released more than 17 albums.
In 2017, Queenzy collaborated with Taiwanese model Tom Chang (張瀚元) to release the single titled "Don't Be Shy" (愛).

Why this record matters
The phrase “malaysian singer and actress” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Sep 6, 2026. The linked authority identifier is Q15079233. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1986, 2023, 2001 and 2017.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
