According to Wang Ming-yang, a lecturer in industrial engineering at National Tsing Hua University, the problem lies in mass production. In a traditional society, where products were made by hand, clothing and everyday items could be custom designed to fit the individual.
清華大學工業工程系講師王明揚指出，在傳統社會中，人們想穿戴些什麼，多半自己動手，衣服、鞋子總是為穿者特別做的，不會有不合身的問題。
