Yumiko Cheng Hei Yee (Chinese: 鄭希怡; born September 6, 1981) is a popular Hong Kong Cantopop singer born in Shanghai. Born Zheng Lieqiong (鄭烈瓊), Cheng was given the Japanese name "Yumiko" by her friends in secondary school.[1] After Cheng signed on with EEG, the name was retained. Yumiko was originally a member of the group 3T (along with Mandy and Maggie Lau), which released an EP in September of 2002.
