This is his self-portrait produced with hair in which Gao takes much pride. After having his hair cut at the age of 90, he collected the hair, glued it on a piece of kraft paper and produced a head portrait. His daughter, Xiaolan, said, "My father is an artist. He can easily create a work of art. I can't come up with such a good idea, not to mention turning it into reality." [Photo by Chen Boyuan/China.org.cn]
