Teng-ko Weng, born in 1960 in Taipei, Taiwan, was raised in an orphanage. To pay for his tuition, Teng-ko worked part time as a street artist and art teacher. His experiences on the street exposed him to a variety of styles and mediums. Teng-ko studied at the Fu Sing Trade School in Taiwan, where he graduated with a Diploma in Fine Arts in 1979. When he was 20, Teng-ko fell ill to meningitis, and lost a part of his hearing. Teng-ko owes his miraculous recovery to his Christian faith. Teng-ko's incredible life experiences and extensive learning process has laid a profound foundation for his art career. He owes his current reputation as a famous artist to his hard life and many experiences.
Weng's work has been met with critical acclaim and he has received several first prize awards. He has published an album of his paintings, an autobiography, and a calendar with his oil paintings. In 1993, he earned a religious artistic award from a Christian art organization in the United States. His works are frequently on display in the art galleries and museums international. Internationally and locally, he's been in many exhibitions, including The Second Annual Christian Arts Festival, in Los Angeles. He has also hosted many solo exhibitions at many places, some of which include: the Pang Pik Gallery (Taiwan), Hao Lai Art Center (Taiwan), Shadbolt Center (Canada), Langley Centennial Museum (Canada), and the Deer Lake Gallery (Canada).
In 1995, Weng emigrated from Taiwan to Canada and now lives in Burnaby with his wife and three children. He is a member of the Federation of Canadian Artists and the Burnaby Art Council and is founder of the Teng-ko Weng art studio.
