Once, Li Han-ching told Tsai that Miao minority dancers in the hometown of his classmate Yao Hao performed a sort of tap dance using cups. When Tsai heard this, she was greatly interested, and got Yao Hao to hum the music and asked the orchestra at the Broadcasting Corporation of China to make a recording based on it.
有一次，學生李清漢告訴蔡瑞月，他的同學姚浩家鄉有人用杯子嗑嗑嗑地跳舞，蔡瑞月聽了大感興趣，找來姚浩哼出音樂，並延請中廣樂團錄製曲子。
