To gain recognition in the international market, Chang Bishi headed a delegation to participate in Panama-Pacific International Exposition (the predecessor of World Expo) in the USA in 1915. At this event, four kinds of Changyu products (i.e. Changyu Keya Brandy, Chefoo Red Rose Wine, Vermouth and Riesling Dry White Wine) won four gold medals. Afterwards, in a speech at the celebrating banquet, Chang Bishi said, “ We Chinese people are really marvelous. As long as we work hard, we as latecomers can surpass the old-timers and make our products famous world wide.”
