Ocean Ou De Yang (Chinese: 歐得洋) is a Mandarin singer about whom little is known. He hid his face for over two years, using computer-generated 3D models for all his album covers and music videos. His real name is Shen Yi-Tseng, and he used to be part of a now defunct three-man band called Y.I.Y.O. Ocean finally revealed his face on November 3, 2005 in a concert in Singapore.
