Cai Rongxing was born into a famous Yilan woodcarving family. His father, Cai Huotu, was the winner of a Folk Art Heritage Award, and Cai learned his superb craftsmanship directly from his father and elder brothers. Besides sculpting temple furniture like his father and brothers, Cai is especially skilled at making cake molds and rice-cake molds. He insists on carving them by hand, and hopes to pass down cake-mold making far into the future.
