Wu Ying Jie (English name Emma), also known by her stage name Gui Gui, is a Taiwanese Mandopop singer and actress represented by Polyland International Entertainment.
In 2006, Gui Gui debuted as one of the original nine members of the Taiwanese girl group "Hei She Hui Mei Mei", which later underwent a name change in their 2008 comeback to "Hey Girl". After a year-long hiatus, Hey Girl launched their first titled debut album. Consisting of eight girls, Hey Girl would often collaborate with the Taiwanese boy band, Lollipop F.
In 2009, Gui Gui left the management of Channel V. Since Hey Girl did not belong to the Channel V Management, Gui Gui was still able to attend the promotional activities per usual. During the summer of 2007, Wu Gui Gui and the other members of Hey Girls made their acting debut in the drama Brown Sugar Macchiato, a collaboration with Lollipop group. This marked as her first acting career.
In early 2011, Gui Gui signed to the new entertainment management company, Polyface Entertainment Media Group, and hoped for a fresh start as she was ready to launch her acting career.
