In 2007, Taipei City mayor Hau Lung-bin was invited to award the prizes to the Universal Design Awards winners, and when he saw the "Who's Cup" design-a disposable cup with bendable, numbered tabs around the bottom to help people remember which cup is theirs-he said to Tang that if they went into production, City Hall would absolutely use them.
2007 年台北市長郝龍斌受邀擔任通用設計比賽的頒獎人，他看到底部可以彎折、印上數字就可以分辨這是誰的紙杯的「Who ' s Cup」時，就對唐峰正說，只要生產出來，市府一定優先採用。
