Anita Mui Yim-fong (Chinese: Mei Yan Fang ; Jyutping: Mui4 Jim6 Fong1; 10 October 1963 - 30 December 2003) was a Hong Kong singer and actress making major contributions to the Cantopop music scene and receiving numerous awards and honours.
1992-2003: Community work
Mui was actively involved in charitable projects throughout her career. According to the posthumous memoirs of democracy activist Szeto Wah, Mui lent significant financial and material support to Operation Yellowbird, to help activists flee from China after the Tiananmen Square protests of 1989.  The Tibetan red-crown Shamar Rinpoche once said "She had a true heart. She was an unconventional woman and brought happiness to lots of people during her life." Her establishment of a nursing home in San Francisco, prompted the mayor of the city in 1992 to name 18 April as "Anita Mui Day". In 1993, she established the "Anita Mui True Heart Charity Foundation" (Mei Yan Fang Si Hai Yi Xin Ji Jin Hui ). That same year, she was also one of the founders of the Hong Kong Performing Artistes Guild. The Canadian city of Toronto declared 23 October 1993 to be "Anita Mui Day".  During the severe acute respiratory syndrome (SARS) outbreak, she initiated a fundraising concert titled the 1:99 Concert to raise money for SARS-affected families. She was also awarded the "Fighting Against SARS Award" from RTHK and the newspaper Ming Pao. In 2003, she wrote and published the book The Heart of the Modern Woman (Xian Dai Nu Ren Xin ). Profits from the book went to the Children's Cancer Foundation.  On 23 September 2004, the Anita Mui True Heart Digital Multimedia Studio was opened at the University of Hong Kong. It included state-of-the-art equipment for digital audio and video editing. In Causeway Bay, an Anita Mui-themed cafe called Happiness Moon (Xi Yue ) is also dedicated to her legacy.
