Frankly these two boys are quite talented.
Not only two of them have performed a song that usually required five white boys with ear pieces, their soundtrack did not skip like Milli Vanilli's during 1990 Grammy Awards.
The duo's name is called 后舍男生 or in English "Back Dormitory Boys". Their spoof music videos have been selected by Motorola China to promote mobile phones.
The Back Dorm Boys are 韦炜 (Wei Wei, height 189 cm or 6'2") and 黄艺馨 (Huang Yi Xin, height 173 cm or 5'8"). They are university students at 广州美术学院 (Guangzhou Arts Institute) majoring in Scupltures.
The third dorm mate in the background is 肖静 (Xiao Jing) and in most of the videos he was playing the computer game "Counter Strike". Here are more info and pictures of them for those who are interested.
