Wu whose father is Filipino-Chinese, was born in Taishan, Guangdong in 1905 and studied art in the 1920's. He returned to Hong Kong in 1936 and began his art and writing career there. In 1946, he taught painting at Ying Wa College, Hong Kong. During his early years, he wrote many works about the beauty of Hong Kong and expressed a vivid life in his works. In the early 1980's, he was invited to teach as a guest professor by Ministry of Culture and Central Academy of Fine Arts, so he had more opportunities to travel around China and painted more landscape paintings. Then he settled down in Canada, devoting himself to diverse cultures, and presented with his painting brushes the natural beauty of lakes and mountains, the scenery of different seasons, and people of all ethnic groups. In the past few years, he had held a 90 Year's Retrospective Exhibition in Taiwan and was highly praised.
