Joyce Chu (born 7 March 1997), nicknamed Siyecao (四葉草, literally "four-leaf clover"), is a Malaysian singer who rose to fame after the music video of her song, "Malaysia Chabor", gained more than 7 million views on YouTube. She is also a member of RED People, a group of artists supervised by controversial rapper-songwriter Namewee.
Chu became a regional internet sensation with her song "Malaysia Chabor", composed by Namewee with information about herself. In the song, she tells others she is a "Malaysian Chabor" (Malaysian girl) and not Korean, as many have assumed her to be. Since June 2014, the video has reached about 7 million views on YouTube, and has spawned covers and parodies by others, especially by a Singaporean recruit consultant, Gary Chun, who made his own version called "Singapore Dapor" in which he showed his affection for Chu.
On 15 October 2014, Chu released a self-composition entitled "Your Little Round Hand" (伸出圆手) for the 100th anniversary of Doraemon. Chu was a guest star at Singaporean talent competition The Ultimate Star Finals, and told The New Paper that she intended to become a singer-actress in Singapore.
Her next song, "Like Me", is on different social media platforms, which is part of Ohhsome CrossXover with Maxis's Hotlink. The music video was uploaded to YouTube on 10 December 2014.
In 2015, it was announced that Chu would be starring in Singapore's first cosplay-themed film, "Young & Fabulous", alongside Aloysius Pang, Jeffrey Xu and Joshua Tan.
