Born in Hunan. Hwang is an expressionist painter in New York. In this period, he used batik and graphic techniques in an abstract surrealistic style, and wrote a book, The Art of Batik. Since 1961, Hwang has held over solo exhibitions and many group shows both in Taiwan and abroad. In 1971, he was invited by the U.S. State Department and the Asian Arts Association to visit the United States. One year later he moved to New York. Hwang has been influenced by Western thought and uses the tension between East and West in conceptualizing his work.
