Whenever Singaporean pop diva Stefanie Sun Yan Zi shows up, her fans go crazy. Her mini farewell concert at the HITEC in Kowloon Bay last week was no exception. When the singer, who is going to take a one-year break, started the show with her hit Green Light, some 1,700 fans greeted her with screams, waving fluorescent sticks in their hands. Sun sang about 10 songs - including her debut hit Cloudy Day on the piano - at the concert, her first in Hong Kong. She also invited fans to the stage to play some games. 'The atmosphere was good. It was happy and warm when everybody sang along with me,' said the 25-year-old, who was not feeling well that day. 'My voice was not that good during the first half of the concert, but it got better gradually.' The singer, who recently revealed her desire to learn more skills by becoming a waitress in New York, said the plan had to be shelved because she could not obtain a work visa. 'To work in New York, you have to get a work permit. I won't do anything illegal,' said Sun, who won four prizes at a recent Asian music awards event in Shanghai. Although Sun will not be producing any records in the coming year, she said she would still take other jobs such as making commercials and going to the mainland to meet fans. 'Most of [my break] will be spent learning things I have always wanted to learn, travelling and watching TV at home,' said Sun, who will start her holiday after attending her record company's 10th anniversary celebration concert in Beijing at the end of this month.
