Meanwhile, "lunatic" Wu Hsing-kuo was similarly amazed at the passion for creativity of this man from Hong Kong. Virtually every piece of cloth, every decorative object, was collected by Yip personally, suitcase in hand, from the Yongle fabric market. Wu says of him, "He spent every last penny of his own on books, not even having enough in his pockets for a cup of coffee."
而「瘋子」吳興國，則同樣驚訝於香港來的「小葉」對創作的狂熱，幾乎每一塊布料、每一種飾件都是他親自拉著皮箱，從永樂市場蒐集而來，他形容「小葉情願把錢拿去買書，口袋裡也經常掏不出買一杯咖啡的錢。」
