While working for periodicals and learning techniques of graphics, screen paintings and engraving, Hu discovered batik and began experimenting with that medium which continued throughout his entire career. Hu moved to Malaysia in 1961 where his career fully developed as a result of the close contact with the Southeast Asian batik industry. He is considered one of the pioneers who helped establish batik painting as an art form in the 1960s. He is also recognized as an innovator in the field, fusing techniques of other art forms with those of batik painting especially combining elements of traditional Chinese art with the batik approach.
Hu has taught at the University of Malaysia since 1969, and has exhibited in Kuala Lumpur, Singapore, Japan, California, and Taipei. He retired to Southern California where he continued exploring other art forms such as paper cutting, brick carving, stone engraving, Western painting, Chinese calligraphy and silk screen printing to mention a few.
