Ekin Cheng is a Hong Kong actor and singer. Early in his career, he used the name Dior as a first name (because that was what it sounded like when his younger sister tried to call him 二哥 in Cantonese). He has also been referred to as Noodle Cheng, ( 鄭伊麵) after a popular noodle dish with a similar name and his wavy long hair.
